The (Y,Gd)BO 3∶Eu phosphor was synthesized by solid state reaction. The UV spectra showed that in a certain range of Gd 3+ concentration, more Gd 3+ absorbed energy and transferred it to Eu 3+ with its increasing concentration. From the spectra in VUV region, it was observed that both the doping and the concentrations of Gd 3+ , Eu 3+ greatly affected the absorption of the host lattice. The absorbances at 147 nm and 170 nm increased when the Gd 3+ was doped which can be explained as that Gd 3+ transferred energy to BO 4. The optical properties of (Y,Gd)BO 3∶Eu were the best when the concentration of Eu 3+ was about 0.04. 展开更多
