Sn~(2+)掺杂高Gd_2O_3硼硅酸盐玻璃的辐照发光性能
|
摘要
在还原气氛下制备了Sn~(2+)掺杂SiO_2-B_2O_3-Gd_2O_3-La_2O_3玻璃,并测试了该玻璃的密度、吸收光谱、光致发光、荧光寿命和X射线激发下的辐照发光。研究结果表明,在SiO_2-B_2O_3-La_2O_3玻璃系统中,随着Sn~(2+)浓度的增大,紫外吸收截止波长红移,荧光强度先增大后因浓度淬灭而减小,在Sn~(2+)浓度为0.3%时达到最大。随着Gd_2O_3逐渐取代La_2O_3,玻璃的密度增大,Sn~(2+)的荧光寿命变短,但未发现Gd~(3+)对Sn~(2+)的敏化增强作用。在X射线激发下,Sn~(2+)的辐照发光强度随着Gd_2O_3浓度的增大而增大,且不因Gd~(3+)浓度淬灭而减小,说明在X射线激发下,Gd~(3+)和Sn~(2+)之间可能存在能量传递。
The Sn~(2+) -doped SiO_2-B_2O_3-Gd_2O_3-La_2O_3 glass is prepared in the reducing atmosphere and its density,absorption spectra,photoluminescence,fluorescence lifetime and radioluminescence excited by X-ray have been tested.The research results show that,in the SiO_2-B_2O_3-La_2O_3 glass system,with the increase of Sn~(2+) concentration,the ultraviolet absorption cut-off wavelength is redshifted,and the photoluminescence intensity first increases and then decreases due to the concentration quenching effect,which reaches the maximum at Sn~(2+) concentration of 0.3 %.With the replacement of La_2O_3 by Gd_2O_3,the glass density increases and the fluorescence lifetime of Sn~(2+) gets shorter,but Gd~(3+)does not show the sensitizing enhancement effect on Sn~(2+) .Under the X-ray excitation,the radioluminescence intensity of Sn~(2+) increases with the increase of Gd_2O_3 concentration and does not decreases under the Gd~(3+)concentration quenching effect,which indicates that maybe there exists the energy transfer between Gd~(3+)and Sn~(2+) under the X-ray excitation.
