Abstract:

Tb3+doped BaZrO3 powders at different Tb3+ concentrations were synthesized by hydrothermal method. The structure, morphology and luminescence properties of the synthesized materials were examined by X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectrum (FTIR) and fluorescence spectrometer, respectively. Parts of hydrothermal products were calcinated to study the effect of temperature on luminescence properties. Analysis results showed that Tb was successfully introduced into the lattice and replaced Zr at B site of perovskite. It was remarkable that all the samples had similar morphology, which was composed of evenly distributed spheres. The broadband emission peaks of the host and the typical emission peaks of Tb3+ were observed in the BaZrO3 doped with Tb3+ under 244 nm excitation, and these peaks reach the maximum at Tb3+ ion content of 5mol%. Temperature had significant influence on their photoluminescence properties. With the calcination temperature increase, the luminescent intensity of Tb3+ doped samples was decreased.
