Summary Of Preparation Methods Of Sulfide Nanocrystallites

The latest technologies of prepration for nanomaterial CdS and application to the materials were summarized. The synthesis of CdS nanomaterials with unique properties has attracted much greater attention in recent years. The nanomaterials of CdS are synthesized by different methods, such as solid, liquid and gas phase reactions. These synthesis methods are reviewed in this paper. It is predicted that nanomaterials method of CdS will become a tendency in future. It′s believed that nano CdS-polymer fluorescent materials can be used in the fields of light, electricity, sensor and photocatalyst due to their performances such as the controlled content, stability, modifiable surface and excellent optical capability and so on, The materials should be studied futher to be realized their applied potential.Zinc sulfide, an important wide band-gap semiconductor, has attracted much attention owing to its wide applications. The preparation of ZnS nanoparticles with unique electrical and optical properties has attracted much greater attention in recent years. The nanoparticles of ZnS are prepared by different methods, such as solid, liquid and gas phase reactions. Every preparation method has its own advantages and disadvantages, and all are reviewed in this thesis. The right method can be selected depending on the applications of ZnS nanoparticles in practice, which, on the other hand, will promote the research on ZnS nanoparticles preparation.
