Abstract
A set of individually and co-doped (): lithium borate glasses were synthesized by melt quenching. Photoluminescence properties were analyzed by excitation, emission, and decay dynamics. 1.5 mol% glass displayed an intense orange emission at 603 nm () under 403 nm excitation. Interestingly, emission was remarkably embellished by the inclusion of ions owing to energy transfer from to . Chromaticity coordinates and correlated color temperatures were tuned from a warm orange to a cool white region in and (): glasses, respectively. These studies suggest that (): lithium borate glasses are favorable candidates for white light emitting diode applications.
