    • Abstract
  • The core-shell CdSe/ZnSe quantum dots were synthesized by hydrothermal method based on the similar crystal structure and wider band gap of ZnSe semiconductor nanomaterial. The effect of reaction temperature, reaction time and molar ratio of Cd:Zn on the synthesis of quantum dots were investigated.Resultsshowed that when the temperature was between 70~160℃, the ZnSe shell was being coated on the CdSe core. When the reaction time was between 0~4 hours, the shell could be uniformly coated on the core. When the molar ratio of core to shell was 1:3, the electrochemical luminescence performance was the best, and its electrochemical luminescence intensity was 6 times higher than that of CdSe quantum dots.
