| 摘 要： | 介孔复合体材料越来越受到人们的关注。通过溶胶-凝胶方法合成出Eosin Y/有序二氧化硅复合体,研究了复合体的光致发光性质。实验发现:随着Eosin Y加入量的增多,光致发光谱峰强度增强。初步探讨了荧光强度增强的机制,认为介孔材料对于Eosin Y分子的锚定作用减少了Eosin Y分子的荧光自促灭效应。

| Abstract: | The materials of mesostructured complex have attracted more attention. The Eosin Y/ordered silica complex was synthesized through the sol-gel method. The photoluminescence property of the complex was studied. It is found that, with the increase of Eosin Y, the PL peak intensity is stronger. The scheme of the increase of the PL peak intensity was discussed. It is aroused by the effect of the PL self-abruptly vanishing was decreased owing to the Eosin Y anchored in the ordered silica structure. |
