Continuous tuning of persistent luminescence wavelength by intermediate-phase engineering in inorganic crystals.

Multicolor tuning of persistent luminescence has been extensively studied by deliberately integrating various luminescent units, known as activators or chromophores, into certain host compounds. However, it remains a formidable challenge to fine-tune the persistent luminescence spectra either in organic materials, such as small molecules, polymers, metal-organic complexes and carbon dots, or in doped inorganic crystals. Herein, we present a strategy to delicately control the persistent luminescence wavelength by engineering sub-bandgap donor-acceptor states in a series of single-phase Ca(Sr)ZnOS crystals.

Sensitive Luminescence Thermometry through Excitation Intensity Ratio in Eu-Doped BaTiO.

Optical ratiometric thermometry techniques have gained much attention in recent years due to their reliable and noncontact temperature sensing capability for industrial and biorelated applications. Herein, we exploited the temperature dependence of the absorption band of BaTiO (BTO) for novel excitation intensity ratio (EIR) thermometry. Photoluminescence and excitation properties of Eu-doped BTO powders were studied as a function of Eu doping concentration.

Interfacing Lanthanide Metal-Organic Frameworks with ZnO Nanowires for Alternating Current Electroluminescence.

Alternating current electroluminescence (ACEL) devices are attractive candidates in cost-effective lighting, sensing, and flexible displays due to their uniform luminescence, stable performance, and outstanding deformability. However, ACEL devices have suffered from limited options for the light-emitting layer, which presents a significant constraint in the progress of utilizing ACEL. Herein, a new class of ACEL phosphors based on lanthanide metal-organic frameworks (Ln-MOFs) is devised.

Intelligent Colorimetric Indicators for Quality Monitoring and Multilevel Anticounterfeiting with Kinetics-Tunable Fluorescence.

The spoilage and forgery of perishable products such as food, drugs, and vaccines cause serious health hazards and economic loss every year. Developing highly efficient and convenient time-temperature indicators (TTIs) to realize quality monitoring and anticounterfeiting simultaneously is urgent but remains a challenge. To this end, a kind of colorimetric fluorescent TTI, based on CsPbBr@SiO nanoparticles with tunable quenching kinetics, is developed.

Develop a Novel Nomogram to Predict Respiratory Failure in Acute Pancreatitis at Early Stage.

Background: Respiratory failure is a common complication in patients suffering from moderately severe or severe acute pancreatitis (AP). The aim of this study was to develop a novel nomogram to predict respiratory failure in AP early.

Methods: Patients, who were hospitalized within 72 hours of AP onset from January 1, 2018, to April 31, 2021 were enrolled in the study.

MicroRNA-21 promotes endometrial carcinoma proliferation and invasion by targeting PTEN.

Endometrial carcinoma is one of the most common gynecological malignant tumors. Recent evidence has demonstrated that miR-21 is involved in the proliferation and invasion of endometrial carcinoma. This study aims to explore the effect of biological behavior of miR-21 on endometrial carcinoma its relationship with PTEN.
