Multifunctional CaF: Yb, Ho, Gd Nanocrystals: Insight into Crystal Growth and Properties of Upconversion Luminescence, Magnetic, and Temperature Sensing Properties.

The upconversion (UC) emission intensity of Ln-doped CaF nanomaterials is not ideal, which limits their application in some advanced scientific fields. Hence, it is extremely imperative to enhance the emission intensity of UC nanocrystals. In this work, an ionic-liquid-assisted hydrothermal method based on an ethylene glycol (EG) and ionic liquid (IL) two-phase system was used to synthesize CaF doped with Yb and Ho.

Systematic Study on the Luminescent Properties, Thermal Stability, and Magnetic Behavior of GdOF: RE (RE = Eu, Yb, and Er) Red Phosphors with Various Morphologies.

In this work, GdOF:RE (RE = Eu, Yb, and Er) phosphors with high thermally stable luminescence were reported, which were synthesized by an ionic liquid-assisted two-phase system and subsequent calcination technique for the first time. Nanodisks, nanorod aggregates, nanoneedles, and stubby nanorods were obtained by simply regulating the pH value. The luminescent properties of precursors and products were discussed in detail.

Exploiting heterologous and endogenous CRISPR-Cas systems for genome editing in the probiotic Clostridium butyricum.

Clostridium butyricum has been widely used as a probiotic for humans and food animals. However, the mechanisms of beneficial effects of C. butyricum on the host remain poorly understood, largely due to the lack of high-throughput genome engineering tools.

SiO:Tb@LuO:Eu Core-Shell Phosphors: Interfacial Energy Transfer for Enhanced Multicolor Luminescence.

Uniform and well-dispersed SiO:%Tb@LuO:%Eu core-shell spherical phosphors were synthesized via a solvothermal method followed by a subsequent calcination process. The structure, phase composition, and morphology of the samples were studied by X-ray diffraction (XRD), thermogravimetric analysis (TGA), Fourier transform infrared spectroscopy (FT-IR), field emission scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The results showed that the LuO:Eu layer was evenly coated on the surface of SiO:Tb spheres and the shell thickness was about 45-65 nm.

Ca(MgAl)(SiAl)O:Ce,Tb Phosphors: Structure Control, Density-Functional Theory Calculation, and Luminescence Property for pc-wLED Application.

A modified structure Ca(MgAl)(SiAl)O (denoted as CMASO) from the evolution of CaMgSiO (denoted as CMSO) codoped with Ce and Tb ions was designed successfully by solid reaction method for application in phosphor-converted white-light-emitting diode (pc-wLED). The Rietveld refinement of these two structures verified the changes derived from the replacement of some of the Mg and Si ions by Al ions. The band gaps were calculated by density-functional theory (DFT) calculation method to verify the change of Al ions replacing further, and the diffuse reflectance spectra (DRS) proved the veracity of the calculation result.

Novel highly efficient single-component multi-peak emitting aluminosilicate phosphors co-activated with Ce, Tb and Eu: luminescence properties, tunable color, and thermal properties.

A series of emission-tunable Ce/Tb/Eu doped Ca(MgAl)(SiAl)O (denoted as CMAS) phosphors have been synthesized via a high temperature solid-state reaction method. The luminescence properties, color tuning, quantum yields (QYs), energy transfer of Ce to Tb/Eu, thermal stability, performance of LED devices and ratiometric temperature sensing application have been systematically investigated, respectively. Importantly, through the study of thermal stability, we found that Ce and Tb co-doped samples were suitable for WLED applications, while Ce and Eu co-doped samples were suitable for temperature sensing applications.

The photoluminescence, thermal properties and tunable color of NaAlSiO:xCe/Tb/Dyvia energy transfer: a single-component multicolor-emitting phosphor.

A series of emission-tunable NaAlSiO:xCe/Tb/Dy phosphors were synthesized via a high temperature solid-state reaction method. Luminescence properties, energy transfer from Ce to Tb or Dy ions, color tuning and thermal stability were systematically investigated. Particularly, the charge compensating defect generated by doping of rare earth ions was remedied through Al substituted Si.

Facile synthesis and color-tunable properties of BaLuF:Ce,Tb,Eu(Sm) submicrospheres via a facile ionic liquid/EG two-phase system.

BaLuF:Ce,Tb,Eu(Sm) submicrospheres were synthesized via an ILs/ethylene glycol(EG) two-phase system. The crystalline phase, size, morphology, and luminescence properties were characterized using powder X-ray diffraction (XRD), field emission-scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), photoluminescence (PL) spectra. The results show that 1-methyl-3-octylimidazolium hexafluorophosphate ([Omim]PF) was used as fluoride source and capping agent to tune morphology and size of the crystals.

Dynamic microwave-assisted extraction coupled with salting-out liquid-liquid extraction for determination of steroid hormones in fish tissues.

In this work, a simple and fast sample pretreatment method was proposed for determination of steroid hormones in fish tissues by coupling dynamic microwave-assisted extraction with salting-out liquid-liquid extraction. The steroid hormones were successively extracted with acetonitrile and water under the action of microwave energy. Subsequently, the extract was separated into an acetonitrile phase and an aqueous phase with ammonium acetate.
