Embodiment Construction
[0013] The preparation of CdTeS quantum dots is divided into three parts: (a) preparation of Te and S stock solutions; (b) synthesis of CdTeS quantum dots; (c) post-treatment.
[0014] (a) Preparation of Te and S stock solutions
[0015] Add 5 mg Te powder and 320 mg S powder into a 25 ml round bottom flask (reactor A), transfer 5 ml OA and 1 ml TOP, and obtain TeS stock solution after dissolving.
[0016] (b) Synthesis of CdTeS quantum dots
[0017] In a 100ml four-neck flask (reactor B), install stirring, a thermometer and an argon protection device, accurately weigh 400mg of CdO, add 20ml of OA, 5ml of TOA and 20ml of TOP, replace the clean air with Ar, and heat up while stirring. When the temperature of reactor B reaches 260-300°C, add stock solution A dropwise, maintain 260°C for 30 seconds, remove the heating device, and when the temperature drops to 100°C, pour the reaction solution into a 100ml Erlenmeyer flask containing 50ml of methanol In (reactor C), seal and sto...
