Synthesis of Zn_0.2Ca_0.8TiO₃:0.1Pr³⁺ by Sol-Gel and its Luminescence Characterization

Abstract:

The Zn_0.2Ca_0.8TiO₃:0.1Pr³⁺ luminescent materials were prepared by sol-gel technology. The phase transformation of gel was studied by TG-DTA and XRD in heat treatment process. The luminescent properties of phosphor in different calcination temperatures were determined by fluorescence spectrophotometer, and then the best sintering temperature was confirmed. The luminescent properties of phosphor was obtained through the emission/ excitation spectra. The surface appearance measured with SEM. The results showed that the nanoZn_0.2Ca_0.8TiO₃:0.1Pr³⁺ phosphor could be obtained by sol-gel, sintering at 900°C. It sent out red fluorescent under the Ultra Violet. This characteristic emission peak at 614nm is associated with the typical ¹D₂³H₄ transition of Pr³⁺ion.
