摘要
采用溶胶凝胶燃烧法在800℃合成了掺杂Ce3+和Tb3+的MgO-Al2O3体系发光材料,比传统高温固相扩散法的合成温度降低了700~800℃.研究了MgO-Al2O3基质当中单掺杂Tb3+及共掺杂Ce3+、Tb3+的发光材料荧光光谱行为,以及恒定温度下时间与浓度对发光材料荧光光谱行为的影响,并对其红外光谱和反应原理进行了探讨.
The luminescence materials of MgO-Al2O3 ： Tb^3 ＋ , Ce^3 ＋ have been synthesized by Sol-gel combustion method at 800℃, that is lower 700--800℃; than that of the high temperature solid method. Behavior of fluorescence spectrum doped different concentration of Tb^3＋ and Tb^3＋/Ce^3＋ in MgO-Al2O3 and effect of heated different time at same temperature have been discussed. IR spectrum and reaction principle are also exploringly explained.
