実験手順

Lead oleate was prepared as follows: lead acetate trihydrate (1 mmol) was mixed with ODE (4 mL) and oleic acid (1.3 mL) in a 50-mL three-neck flask. The mixture was degassed under vacuum (˜50 mTorr) at RT for 10 minutes and then gradually heated to 85° C. and kept for 1 hour to further remove the water and acetic acid. After the mixture turned colorless, the vacuum was removed and the lead-oleate solution was cooled to room temperature. The lead-oleate solution was mixed with TOP (8 mL) and SeO2 (1 mmol). Under argon flow and with stirring, the resulting mixture was heated to 180° C. After 5 min at the temperature, the reaction was terminated by cooling the reaction solution to room temperature. The resulting PbSe nanocrystals were precipitated from the reaction solution using acetone and redispersed in toluene.
