Embodiment 1
[0027] This embodiment provides a method for preparing an aqueous phase ternary quantum dot cadmium indium selenide, comprising the following steps:
[0028] (1) Add 0.3155g selenium powder, 6mL deionized water and 0.34g NaBH to the serum bottle in sequence 4 , a rubber stopper with a syringe needle inserted on the stopper, reacted under magnetic stirring to obtain a colorless and transparent solution A;
[0029] (2) Dissolve 100mL of 0.01M Cd(NO 3 ) 2 solution and 100mL 0.01M In(NO 3 ) 3 The solution was added into a three-necked flask, and stirred evenly to obtain solution B;
[0030] (3) Add 421.8 μL of 3-mercaptopropionic acid to the solution B, then adjust the pH to 10.00 with 1M NaOH solution; use a syringe to get 0.6 mL of the solution A and quickly inject it into the three-necked flask, and wait for the reaction to stabilize. Heating to reflux at 100° C. for 2 hours to obtain the cadmium indium selenide quantum dot solution.
