Optical Properties of LiIn(1−𝑥)Tm𝑥(WO4)2 Blue Phosphor
LiIn1−𝑥Tm𝑥(WO4)2 (𝑥=0, 0.5, 1, 5, and 10 at.%) polycrystalline powders blue phosphors were prepared via the classical solid-state reaction method. X-ray diffraction (XRD), scanning electron microscope (SEM), photoluminescence excitation, and emission spectra were used to characterize LiIn1−𝑥Tm𝑥(W...
