英文摘要:
Color conversion glass ceramics are prepared by cosintering borosilicate glass frits and green 0.06Ce:Y-2.94(Al1-xGax)(5)O-12 phosphors. The crystal structures, the influence of Ga concentration on the photoluminescence (PL), and reliability properties of the color conversion glass ceramics are investigated. The PL emission wavelengths of 0.06Ce:Y-2.94(Al1-xGax)(5)O-12 glass ceramics show blue shift from 545 nm to 525 nm with increasing Ga content (x value) under excited at 460 nm. Reliability test results show that the quantum yield (QY) of 0.06Ce:Y-2.94(Al1-xGax)(5)O-12 glass ceramics decreases from 70.60% to 59.06% with x value increasing from 0.15 to 0.35 under the ambient condition of 85 degrees C/RH85% for the exposure time of 168 h. And the quantum yield (QY) of 0.06Ce:Y-2.94(Al1-xGax)(5)O-12 glass ceramics decreases from 65.13% to 52.23% after being soaked into boiled water for 4 h. The finding reveals that the addition of Ga can deteriorate the reliability of the color conversion glass ceramics.
