Abstract

The purpose of this work is to investigate the basic electrical properties of  type –II  CdTe/CdS/ZnS core/shell/shell quantum dot  to explore the use in all- inorganic light emitting diodes towards the application in optoelectronic devices. It was based on the development of colloidal quantum dots consisting of semiconductor nanocrystals which provided potential electroluminescence devices. The use of nanocrystals allows the emission wavelength to be tuned to cover a wide range of wavelengths. Suggestions have been given for the future research in this direction.
