Constructing Broadband Near-Infrared Garnet Emitters CaGdGaSiO:Cr with Unity Quantum Efficiency and High Thermal Stability for Versatile Applications.

The pursuit of broadband near-infrared (NIR) phosphors for next-generation smart NIR light sources has garnered extensive interest. However, developing phosphors efficiently excitable by blue light to produce thermally stable and highly efficient broadband NIR emission surpassing 830 nm remains a formidable challenge. Herein, a novel CaGdGaSiO garnet is reported, designed through a structure reconstruction approach to host Cr ions for developing a high-performance broadband NIR phosphor.

Achieving broadband near-infrared emission with superior anti-thermal quenching by optimizing the excited-state population of Cr in GdScGaO garnet phosphors.

Cr-activated garnet phosphors with broadband near-infrared (NIR) emission have attracted considerable interest due to their high quantum efficiency (QE) and thermal stability for widespread advanced applications. Nevertheless, how to achieve energy-saving broadband NIR phosphors that possess anti-thermal quenching (anti-TQ) without compromising the high QE has yet to be fully addressed. Herein, we report on site reconstruction within the garnet lattice by strategically positioning Sc and Ga atoms into octahedral B sites with a mole ratio of 1 : 1 to produce GdScGaO.

Unlocking Cr-Cr Coupling in Spinel: Ultrabroadband Near-Infrared Emission beyond 900 nm with High Efficiency and Thermal Stability.

Broadband near-infrared (NIR) phosphor-converted light-emitting diodes (pc-LEDs) hold promising potential as next-generation compact, portable, and intelligent NIR light sources. Nonetheless, the lack of high-performance broadband NIR phosphors with an emission peak beyond 900 nm has severely hindered the development and widespread application of NIR pc-LEDs. This study presents a strategy for precise control of energy-state coupling in spinel solid solutions composed of MgZnGaO to tune the NIR emissions of Cr activators.

Boosting broadband short-wave infrared emission to achieve near-unity quantum efficiency bridging Cr-Ni in spinel solid-solutions towards light-emitting diode applications.

Recently, short-wave infrared (SWIR) phosphor-converted light-emitting diodes (pc-LEDs) have garnered increased attention due to their widespread applications in night vision, biological imaging, and non-destructive testing. Nevertheless, the currently used SWIR phosphors suffer from poor thermal stability and low quantum efficiency. In this study, a finely tuned spinel-based solid solution, MgZnGaO, is prepared to host Ni to induce SWIR emission.

All-inorganic Mn-doped metal halide perovskite crystals for the late-time detection of X-ray afterglow imaging.

All-inorganic metal halide perovskite (MHP) materials have been widely studied because of their unique optoelectronic properties, whereas there has been little research reported on their X-ray afterglow imaging properties. Herein, we report the design and synthesis of Mn-doped hexagonal CsCdCl MHP crystals with excellent X-ray scintillation and X-ray induced afterglow. The orange emission from Mn shows a red shift due to the strong interaction of the Mn-Mn dimers formed at higher doping concentrations.

Effects of age-related changes in trunk and lower limb range of motion on gait.

Background: The ability to walk is crucial for maintaining independence and a high quality of life among older adults. Although gait characteristics have been extensively studied in older adults, most studies have investigated muscle activity in the joints of the trunk or the lower limbs without assessing their interactions. Thus, the causes of altered trunk and lower limb movement patterns in older adults remain to explore.

Near-Infrared Long Afterglow in Fe-Activated MgSnO for Self-Sustainable Night Vision.

Ni-Doped Garnet Solid-Solution Phosphor-Converted Broadband Shortwave Infrared Light-Emitting Diodes toward Spectroscopy Application.

Broadband shortwave infrared (SWIR) light-emitting diodes (LEDs), capable of advancing the next-generation solid-state smart invisible lighting technology, have sparked tremendous interest and will launch ground-breaking spectroscopy and instrumental applications. Nevertheless, the device performance is still suppressed by the low quantum efficiency and limited emission bandwidth of the critical phosphor layer. Herein, we report a high-performance Ni-doped garnet solid-solution broadband SWIR emitter centered at ∼1450 nm with a large full-width at half-maximum of ∼300 nm, thereby fabricating, for the first time, a directly excited Ni-doped garnet solid-solution phosphor-converted broadband SWIR LED device.

[Effects of Straw Mulching and Nitrogen Reduction on the Distribution of Soil Nitrogen and Groundwater Nitrogen Pollution].

To explore the effects of straw mulching and reduced nitrogen fertilization on the temporal and spatial patterns of soil nitrogen, groundwater nitrogen pollution, and summer maize yield, field experiments were carried out in the Hetao irrigation district in 2017 and 2018. The experiment involved the following seven treatments:a control (CK) treatment involving conventional fertilization and traditional tillage, and conventional nitrogen applications reduced by 30% (N1), 20% (N2), and 10% (N3) coupled with either straw surface covering (B) or deep straw burial (S). The results showed that the distribution of soil nitrogen in the CK treatment varied depending on soil depth, with an overall decreasing trend.

The effects of straw mulching combined with nitrogen applications on the root distributions and nitrogen utilization efficiency of summer maize.

To provide an appropriate tillage fertilization model for improving N utilization efficiency and increasing production, the field experiments were conducted to study the effects on root distributions and N utilization efficiency of summer maize involving different straw mulching modes combined with N fertilization. No (N0), low (N1), medium (N2), and high (N3) levels of N fertilization were incorporated into soil combined with the surface coverage straw (Treatment B) and the deeply buried straw (Treatment S). The traditional cultivation was used as control treatment.

Tailoring Multidimensional Traps for Rewritable Multilevel Optical Data Storage.

In the current "big data" era, the state-of-the-art optical data storage (ODS) has become a front-runner in the competing data storage technologies. As one of the most promising methods for breaking the physical limitation suffered by traditional ones, the advance of optically stimulated luminescence (OSL) based optical storage technique is now still limited by the simultaneous single-level write-in and readout in a same spot. In this work, to bridge the data-capacity gap, we report for the first time a novel and promising nonphysical multidimensional OSL-based ODS flexible medium for erasable multilevel optical data recording and reading.

Crystal field modulation-control, bandgap engineering and shallow/deep traps tailoring-guided design of a color-tunable long-persistent phosphor (Ca, Sr)GaO:Mn,Bi .

In this paper, a new color tunable long persistent phosphor (Ca, Sr)Ga4O7:Mn2+,Bi3+ has been successfully synthesized via a high-temperature solid-state reaction. Crystal field modulation and band gap engineering controlled by Sr2+ substitution for Ca2+ realizes the color tunable Mn2+ emission from 580 to 556 nm. Guided by the tailoring of traps distribution, the long persistence luminescence (LPL) performance of CaGa4O7:Mn2+ is greatly enhanced to 33 times higher brightness and much longer persistent time through Bi3+ co-doping.

Attentional biases toward body images in males at high risk of muscle dysmorphia.

Objective: Although research on muscle dysmorphia (MD), a body dysmorphic disorder subtype, has recently increased, the causes and mechanisms underlying this disorder remain unclear. Results from studies examining disorders associated with body image suggest the involvement of self-schema in biasing attention toward specific body information. The present study examined whether individuals at higher risk of MD also display attentional biases toward specific types of body images.
