摘要

采用溶胶-凝胶法在低温、还原气氛下制备了长余辉发光材料Sr

∶ Eu

。用X射线粉末晶衍射对其进行了物相鉴定

表明在1 200 ℃已经得到纯相的Sr

产物。研究了铕和锶的比值、激发光波长对所制备的Sr

∶ Eu

发光性能的影响并对其影响机理进行了探讨。样品的发光性能测试结果表明:采用溶胶-凝胶法制备长余辉发光材料Sr

∶ Eu

其灼烧温度比高温固相法灼烧温度低;激发光谱向长波方向延伸时

在488 nm处发射峰增强

在410 nm处发射峰减弱;在一定范围内发光强度随着Eu

量的增加而增强

的最佳掺杂量为0.007

的掺杂量超过0.007时会发生浓度猝灭。

Abstract

Sol-gels have been used to prepare Sr

∶ Eu

under low temperature at reducing atmosphere. The XRD shows that the production prepared at 1 200 ℃ is pure phase of Sr

. Effects of some factors such as different Eu-to-Sr ratio and excitation wavelength were studied

the impact mechanism were also discussed. The obtained results indicate that: sintering temperature of sol-gel method is lower than that of high temperature solid-phase method. The excitation spectra were shifted to the long-wavelength

the 488 nm and 410 nm emission peaks were enhanced with an optimal molar ratio of 0.007 Eu

.When the concentration is larger than 0.007

concentration quenching will occur.
