摘要

利用溶胶-凝胶法结合气氛控制合成了含Cu 7.2 S 4 量子点的玻璃. 通过热重-差热分析仪对干凝胶样品的热分解机制进行了分析, 并利用X射线粉末衍射仪、 X射线光电子能谱、透射电子显微镜、 X射线能量色散谱)、高分辨透射电子显微镜及选区电子衍射对 Cu 7.2 S 4 量子点在玻璃中的微结构进行了表征, 利用飞秒 Z 扫描技术研究了材料在800 nm的三阶非线性光学性质. 结果表明, 尺寸在9~21 nm之间的Cu 7.2 S 4 纳米晶已经在玻璃中形成, 该玻璃展示出了优异的三阶非线性光学性能, 其三阶非线性光学折射率( γ )、三阶非线性吸收系数( β )和三阶非线性极化率[ X (3) ]分别为1.11×10 -15 m 2 /W, 8.91×10 -9 m/W和9.56×10 -18 m 2 /V 2 .
