Abstract

Polymers and glasses doped with small semiconductor clusters represent a new class of materials. These materials are interesting for two reasons. First, the size of the semicondutor clusters can be controlled to vary from a few to hundreds of Å. This provides a vehicle to study the transition of a semiconductor from molecular to bulk. Secondly, by doping polymers or glasses with these small semiconductor clusters, utilizing their large resonant third order nonlinearity, new optically nonlinear composite materials can be prepared. In this paper we will discuss the linear and nonlinear optical properties of PbS and CdS clusters in polymer films.
半导体团簇的线性和非线性光学性质
掺杂小半导体团簇的聚合物和玻璃代表了一类新的材料。这些材料之所以有趣,有两个原因。首先,半导体集群的大小可以控制在几个到几百个Å之间。这为研究半导体从分子到体的转变提供了一种载体。其次,通过在聚合物或玻璃中掺杂这些小半导体团簇,利用其大的共振三阶非线性,可以制备新的光学非线性复合材料。本文讨论了聚合物薄膜中PbS团簇和CdS团簇的线性和非线性光学性质。
