Abstract

The crystalline Eu_0.25Y_1.75SiO₅ (EYSO) fine powders were prepared using metallorganic decomposition process, in which the pure X_1- and X_2-Y₂SiO₅ phases were obtained by calcining at temperatures from 850°C to 1600°C. The influence of calcining temperature on photoluminescence (PL) and thermal quenching were systematically investigated from room temperature to 573K for the first time. As a consequence, the X₂-EYSO was higher in light emission intensities than the X₁-EYSO, but the X₁-EYSO possessed better temperature dependence of PL. The phase structure had a significant effect on the light emission intensity and energy as well as its temperature characteristics in the EYSO.
