Abstract
Utilizing a facile sol-gel reaction route, we dealt with the fabrication and luminescent properties of Sm3+-activated Y2Mo4O15 red-emitting microparticles. At the excitation of 405 nm, the resultant microparticles showed visible red emission with color purity of 76.7%. According to the detected decay time, the theoretical internal quantum efficiencies of the compounds were analyzed. In addition, temperature-dependent emission spectra were performed to verify the thermal resistance performances of the microparticles. As proof of the suitability of the prepared compounds for solid-state illumination, a white light-emitting diode (WLED) device was packaged using the obtained microparticles, BaMgAl10O17:Eu2+ blue phosphors, (Ba,Sr)2SiO4:Eu2+ green phosphors and near-ultraviolet (NUV) chip. The designed WLED lamp enabled emit bright white light with a good chromaticity coordinate of (0.302, 0.394), satisfied color rendering index (78.3) as well as proper correlated color temperature (6552 K).
