| Abstract: | Chitosan-coated CdSe quantum dots (CdSe/CS QDs) were successfully synthesized in aqueous system through a γ-radiation route at room temperature under ambient pressure. The diameter of the resulting QDs was about 4 nm with narrow size distribution. The synthesized QDs exhibited an absorption peak at 460 nm and an emission peak at 535 nm. These QDs were cubic zinc blende CdSe in core structure and coated with chitosan on surface, with fine solubility in water. |
