The isostructural 3D lanthanide metal–organic frameworks reveal better luminescence sensing properties for the detection of Fe 3+ ions and Cr 2 O 7 2− anions.
β-phase gallium oxide (β-Ga 2 O 3 ) is an extra wide-bandgap semiconductor that has garnered significant attention for its immense potentials in high-power electronic and optoelectronic applications. However, the high electron concentration due...
The influence of Cr 3+ on the down-conversion luminescence (DCL) β-PbF 2 :Er /Yb /Cr glass–ceramic composites was studied.
We investigate UV photorefraction in Mg-doped LiNbO3 crystals. Strong is achieved highly crystals with high two-wave mixing gain, fast response, and low noise. It also demonstrated experimentally that so-called damage-resistant dopants such as Mg are damage resistant only the visible they will enhance UV.
Rare-earth doped oxyfluoride glasses and nanocrystalline glass ceramics have been prepared studied by energy dispersive X-ray spectroscopy (EDS) diffraction (XRD) aiming at investigating the structure symmetry of nanocrystal as well site rare-earth ion. To solve problem encountered previous researchers due to host interference, we etched off matrix released fluoride nanocrystal, which is more convenient for EDS measurement. A tetragonal phase model with chemical formula PbREF(5) proved...

In quantitative study, a randomized controlled trial performed 40 participants divided into control group (n = 20) an intervention 20). The Self-rating Anxiety Scale, Depression Scale Pittsburgh Sleep Quality Index were compared. For qualitative analysis, it adopted...
A series of rare earth (RE) doped oxyfluoride glasses with the composition (45-x) SiO2-5Al2O3-40PbF2-10CdF2-xRe2O3 (x = 1, 5, 10, 15) (mol%) were prepared by a traditional melt-quenching method. Glass ceramics (GCs) obtained after thermal treatment and characterized X-ray diffraction (XRD) to investigate nanocrystal structure distortion. Both dopant type doping level play an important role in distortion PbF2-RE lattice. It is found that cubic Pb3REF9 phase forms low GCs, tetragonal PbREF5...
