Compound films embedded with GaAs semiconductor nano-particles were successfully prepared by means of radio frequency (RF) magnetron co-sputtering technology.

Research topics and future directions in the field of nanometer semiconductor particle thin films are also presented.

This paper reviews some methods for constructing semiconductor nanoparticles/PANI composite materials,which were developed by us in recent years.

The prepara- tion and characterization of metal nanoparticle and semiconductor nanoparticle on monolayers are introduced.

In-situ preparation of semiconductor nanoparticles in polymer network, surface modification of nanoparticles with organic or inorganic molecules and assembly of nanoparticles in bulk or film materials are introduced in this article.

Semiconductor nanoparticles, which own large nonlinear refractive index and fast response speed, have been extensively studied in the last decades.

Semiconductor nanoparticles possess many unique optical properties, high surface-to-volume ratio and other properties related to their nanometer dimension.

Semiconductor nanoparticles have a narrow, tunable, symmetric emission spectrum and a broad, continuous excitation spectrum.

This thesis focuses on liquid crystal materials doped with semiconductor nanoparticles, which means obtaining liquid crystal devices with low-power features via doping.
