文摘

Tm3+/Tb3+/Sm3+ tri-doped transparent borate glasses were successfully synthesized via melt quenching technique, and the optical and luminescent properties were characterized by photoluminescence excitation, photoluminescence spectra, absorption spectra, decay time and chromaticity coordinates. The energy transfer of Tm3+, Tb3+ → Sm3+ in Tm3+/Tb3+/Sm3+ co-doped glass samples was demonstrated. The chromaticity coordinate (x = 0.3339, y = 0.3241) and color correlate temperature (CCT = 5420.73 K) close to the standard white light (x = 0.3333, y = 0.3333 and CCT = 5454.12 K) could be achieved in 0.4Tm3+/1.0 Tb3+/0.8Sm3+ (mol %) tri-doped glass sample. It is expected that the investigated glasses may be a promising candidate for white-light-emitting diodes, luminescent materials and fluorescent display devices.
