Abstract

Abstract: The (Y,Gd)BO₃;Eu phosphor was synthesized by solid state reaction. The UV spectra showed that in a certain range of Gd³⁺ concentration, more Gd³⁺ absorbed energy and transferred it to Eu³⁺ with its increasing concentration. From the spectra in VUV region, it was observed that both the doping and the concentrations of Gd³⁺ , Eu³⁺ greatly affected the absorption of the host lattice. The absorbances at 147 nm and 170 nm increased when the Gd³⁺ was doped which can be explained as that Gd³⁺ transferred energy to BO₄. The optical properties of (Y,Gd)BO₃;Eu were the best when the concentration of Eu³⁺ was about 0.04.

Key words: Y,Gd)BO₃, Eu, VUV Spectrum, Host lattice absorption band
