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
