Embodiment 1
[0028] (1) Operate in a glove box. In a 50mL three-necked round-bottomed flask, weigh and add 32mg of triphenylphosphine gold chloride, 22mg of silver nitrate, and 28mg of indium chloride, and measure 10mL of oleylamine for mixing. Finally, place the three-necked bottle in a magnetic heating stirrer, connect the temperature probe to the left side, connect the reflux condenser to the middle port, and connect the reverse plug to the right side, heat up to 80°C while magnetically stirring, and repeat the operation 3 times , each vacuuming time is at least 10min, so that the vacuum degree of the system reaches -0.1MPa, and then heated to 130°C under a nitrogen atmosphere, and reacted at a constant temperature for 0.5h, and then continued to heat up to 180°C, and kept at a constant temperature for 10min.
[0029] (2) Add 22mg of selenium powder and 10mL of oleylamine into a 50mL three-neck round bottom flask, and disperse it ultrasonically at room temperature for 10 minutes. The mi...
Embodiment 2
[0035] (1) Operate in a glove box. In a 50mL three-neck round bottom flask, weigh and add 10mg of triphenylphosphine gold chloride, 11mg of silver nitrate, and 28mg of indium chloride, and measure 10mL of oleylamine for mixing. Finally, place the three-neck bottle in a magnetic heating stirrer, connect the temperature probe to the left side, connect the reflux condenser to the middle port, and connect the reverse plug to the right side, heat up to 80°C while magnetically stirring, and repeat the operation 3 times , each vacuuming time is at least 10min, so that the vacuum degree of the system reaches -0.1MPa, and then heated to 130°C under a nitrogen atmosphere, and reacted at a constant temperature for 10min, and then continued to heat up to 180°C, and kept at a constant temperature for 2h.
[0036] (2) Add 11mg of selenium powder and 10mL of oleylamine to a 50mL three-neck round bottom flask, and disperse it ultrasonically at room temperature for 10 minutes. The middle port ...
