DOI: 10.1016/j.apt.2019.12.016

Abstract: Abstract Novel up-conversion luminescent SrGd2(WO4)2(MoO4)2: Yb3+/Tm3+/Ho3+ nano-crystals were synthesized by hydrothermal method. The composition ratio of rare earth had been investigated. It indicated that when CYb3+ = 10 mol% and CYb3+/CTm3+/CHo3+ = 10:1.5:2, the emission intensities were the highest. X-ray… read more here.

DOI: 10.1016/j.jssc.2019.01.033

Abstract: Abstract Hydrothermal process was employed to synthesize the Yb3+/Tm3+, Yb3+/Ho3+ and Yb3+/Tm3+/Ho3+ doped BaMoO4 octahedron microcrystals (0.50–5.0 µm). The synthesized phosphors have scheelite tetragonal structure. The elemental mapping suggests the uniform distribution of elements in the… read more here.

DOI: 10.1016/j.optmat.2017.06.045

Abstract: Abstract Y3Al4GaO12 (YAGG):(Tm3+, Ho3+) nanoparticles have been synthesized by Pechini sol-gel method and characterised their X-ray diffraction patterns, scanning electron microscope image, energy dispersive and photoluminescence spectra. From XRD results, phase purity and structure have… read more here.
