Abstract
Ce:YAG phosphor in glass was prepared by co-sintering bismuthate glass frits and Ce:YAG phosphors at different temperatures in the 550–800 °C range. In this work, the effect of co-sintering temperature on the photoluminescence and chromaticity coordinates (CIE) of phosphor in glass was investigated. The results show that the CIE coordinates is tunable with the increase of co-sintering temperature. As temperature increased from 550 to 700 °C, the intensity of emission and excited peak increases until a maximum is reached, after which it rapidly drops off. The degradation of luminescence properties with the higher co-sintering temperature is due to the broken lattice surrounding the Ce3+ and oxidation of the Ce3+ caused by the reactions between the bismuthate glass and Ce:YAG phosphors.
