Effect of sintering temperature on the photoluminescence characteristics of the Nd2O3-doped SnSiO4 phosphor

摘要

In this study, Nd2O3 was used as the dopant and the commercial Sr2SiO4:Nd phosphors was produced by using solid-state reaction method. The Sr2SiO4:Nd phosphors was sintered at the temperature range of 1000°C~1300°C for 2 h. From the results of X-ray diffraction patterns, even sintered at 1000°C only Sr2SiO4 phase was observed, no secondary and unknown phases were residual in the calcined Sr2SiO4:Nd powders. We had found that the sintering temperature had large effect on the luminescence characteristics of the Nd2O3-doped Sr2SiO4 phosphors. The CIE colorimetric data of Sr2SiO4:Nd phosphors as a function of sintering temperature was also investigated in this study. We found that the Sr2SiO4:Nd phosphors revealed a dark blue or a ultraviolet light.
