| 摘 要： | 通过控制Dy3+的掺杂浓度,制备出了不同浓度的Eu2+,Dy3+单掺和共掺高硅氧发光玻璃,测试其激发和发射光谱,讨论了Dy3+浓度对Eu2+,Dy3+共掺样品发光性质的影响。结果表明,Eu2+,Dy3+共掺高硅氧发光玻璃中存在Dy3+向Eu2+的无辐射能量传递现象,且Dy3+的引入会使高硅氧发光玻璃中Eu—O的共价作用减弱,造成Eu2+发射峰蓝移;随着Dy3+浓度的增加,Dy3+→Eu2+能量传递增强,Eu2+发光增强;Dy3+含量继续增加,则Dy3+发光出现浓度猝灭,且Dy3+→Eu2+能量传递减弱。 |

| Abstract: | Eu2+ doped, Dy3+ doped and Eu2+,Dy3+ co-doped high silica luminescence glasses were prepared. By controlling the doping concentration of Dy3+, the different mole ratios of Dy3+ to Eu2+ were researched. The effect of Dy3+ on luminescence properties of Eu2+,Dy3+ co-doped high silica glass was studied by means of excitation and emission spectra. The results show that nonradioactive energy transfer from Dy3+ to Eu2+ occurred in Eu2+,Dy3+ co-doped high silica glass. By co-doping with Dy3+, the covalent strength of the Eu-O bond weakened, which causes blue shift of the emission peak of Eu2+. With the increasing concentration of Dy3+, the energy transfer process from Dy3+ to Eu2+ is enhanced, and the emission intensity of Eu2+ increase. When the concentration of Dy3+ continued increase, the luminescence of Dy3+ decrease because of the effect of concentration quenching and the impaired energy transfer process from Dy3+ to Eu2+. |
