Photoluminescence characteristics of perovskite Eu-doped (Ba0.9Sr0.1)ZrO3 ceramic

摘要

In these BaZrO3-based phosphors, more research works concentrated upon Eu-doped BaZrO3, which is a red-orange long-lasting material. In this study, the solid-state reaction method was used to synthesize the (Ba0.9Sr0.1)ZrO3:Eu0.025 (BSZO-Eu) ceramic was synthesized at the temperature range of 1000°C-1400°C for 2 h. We had found that the optimum excitation optical wavelength of the BSZO-Eu powders were 271 nm and the maximum intensity of the emission spectrum of the BSZO-Eu powders increased with increasing sintering temperature.
