英文摘要:
Colour conversion glasses were prepared by cosintering borosilicate glass frits and Ce:YAG phosphors at various temperatures in the 600-900 degrees C range. The effect of hydrogen annealing on the photoluminescence (PL) of the colour conversion glasses was investigated. The relative photoluminescence (PL) intensity of the colour conversion glasses sintered at 600-800 degrees C was significantly enhanced from 4.87% to 225.61% after hydrogen annealing for 3 h. However, changes to the relative PL intensity of the colour conversion glasses sintered above 850 degrees C after hydrogen annealing were miniscule, because the corrosion of the glass matrix disturbed the YAG lattice. The findings revealed that hydrogen annealing improved the PL intensity of the colour conversion glasses only when the crystal structure of YAG was intact. (C) 2016 Published by Elsevier B.V.
