Abstract

A process for preparing the cadmium sulfide nanorods includes proportionally adding mercaptoacetic acid to the solution containing cadmium ions, stirring, proportionally adding sodium sulfide, reaction at 100-500 deg.C for 1-200 hr, centrifugal treating, and drying. Its advantage is no environmental pollution.

Description

technical field [0001] The invention relates to a preparation method of cadmium sulfide nanorods Background technique [0002] Cadmium sulfide is an important semiconductor material, which is widely used in optoelectronic fields such as solar cells and light-emitting diodes. Recently, due to the development of nanotechnology, nano-cadmium sulfide has some properties that cadmium sulfide thin films and bulk materials do not have, such as a single cadmium sulfide nanorod emitting blue laser light, etc., so nano-cadmium sulfide has attracted widespread attention. However, the preparation of cadmium sulfide nanorods in large quantities, effectively and at low cost is a prerequisite for ensuring the wide application of cadmium sulfide nanomaterials in the field of optoelectronics in the future. At present, there are many methods for preparing cadmium sulfide nanorods, such as template-assisted electrochemical method, thermal evaporation method, laser ab...
