Solution Phase Synthesis and Photoluminescent Properties of Nanocrystal LaPO_4:Eu~(3+)

摘要

Nanocrystal, 6.8 sized, of LaPO_4:Eu~(3+) has been successfully synthesized via a simple solution phase method. The influence of temperature preparation on the photoluminescent properties of LaPO_4:Eu~(3+) (700，900, 1000 and 1100 °C) was investigated under UV radiation. It was observed from the photoluminescence spectra for LaPO_4:Eu~(3+)，the emission transition D_0~5-F_1~7 was found to be more prominent over the normal red emission transition D_0~5-F_2~7. The temperature of 1100°C did not achieve the temperature quenching of luminescent properties of as-prepared LaPO_4:Eu~(3_).
