1 引言随着高新技术的发展,光电子学对非线性光学材料的需要愈来愈迫切。自从日本物理学家久保亮五首次提出金属纳米粒子的“Kubo效应”以来,纳米材料的研究异常活跃。纳米材料的研究已从金属粒子扩展到金属氧化物、极性化合物和半导体等。纳米复合材料提供了一种最容易的方式来研究低维量子阱材料(量子点、量子线等)。0—3nm复合材料就是将0维的量子点分散在3维的基体里面。3维的基体有玻璃、聚合物、无机
1 Introduction With the development of high-tech, optoelectronics for nonlinear optical material needs more and more urgent. Since the Japanese physicist Kubo five proposed the “Kubo effect” of metal nanoparticles for the first time, the research of nanomaterials has been extremely active. Research on nanomaterials has expanded from metal particles to metal oxides, polar compounds and semiconductors. Nanocomposites provide one of the easiest ways to study low-dimensional quantum well materials (quantum dots, quantum wires, etc.). 0-3nm composite material is the 0-dimensional quantum dots dispersed in the three-dimensional matrix inside. The three-dimensional matrix is glass, polymer, inorganic
