纳米材料是低维材料的一种,是目前材料科学研究的热点和前沿.纳米复合材料因具有很强的非线性光学效应而引起人们的兴趣.1983年Jain和Lind首先发现掺有Cd(SSe)的玻璃具有较高的三阶非线性极化率和高的响应速率,Cd(SSe)的尺寸被估计为10～100nm.这揭开了半导体掺杂纳米复合材料的研究序幕.多年来有许多人从事这方面的研究工作,日本的Nogami等研究了CdS,PbS,CuCl,CdTe等分散在SiO_2玻璃中的复合材料的量子尺寸效应和吸收光谱.西安交通大学电子材料研究所在这方面作了大量的研究工作,制备了一系列化合物牛导体微晶与多孔SiO_2玻璃的复合材料,并且研究了复合材料的结构与特性。
Nanomaterials are a kind of low-dimensional materials and are currently the hot and frontier of material science research.Nano-composites have aroused people's interest due to their strong nonlinear optical effect.In 1983, Jain and Lind first discovered that Cd (SSe ) Have higher third-order nonlinear polarizabilities and high response rates, and the size of Cd (SSe) is estimated to be 10 ~ 100 nm. This reveals the research progresses of semiconductor-doped nanocomposites. For many years, Many people engaged in this research work, Japan's Nogami such as CdS, PbS, CuCl, CdTe and other dispersed in the SiO 2 glass composite materials, quantum size effect and absorption spectra. Xi'an Jiaotong University Institute of Electronic Materials in this regard A large number of research work was done to prepare a series of compound cowhide microcrystals and porous SiO 2 glass composites, and the structure and characteristics of the composites were studied.
