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.

Abstract

A gold and silver indium selenide heterostructure rod-shaped nanocrystal and a synthesis method thereof relate to the nanocrystal. The heterostructure rod-shaped nanocrystals of gold and silver indium selenium are Au-AgInSe 2 Heterostructure rod-like nanocrystals with Au nanoparticles as the head end and AgInSe grown on the other end 2 Nanorod heterostructures. Mix triphenylphosphine gold chloride, silver nitrate and indium chloride with oleylamine, vacuumize, blow nitrogen, heat up and react, and then get dark red gold nanoparticles mixed with oleylamine complexes of copper salt and indium salt solution; add selenium powder into oleylamine, vacuumize, ventilate nitrogen, heat up and heat to react, and obtain a reddish-brown transparent selenium oleylamine solution; inject the prepared selenium oleylamine solution into gold nanoparticles and copper salt Mix the solution with the oleylamine complex of indium salt, keep heating and stirring to obtain a gray-black turbid solution, then heat the reaction, centrifuge, and after the obtained precipitate is washed, the heterogeneous rod-shaped nanocrystal of gold and silver indium selenium can be obtained.

Description

technical field [0001] The present invention relates to nanocrystal, relate in particular to a kind of heterostructure rod nanocrystal of gold and silver indium selenide (recorded as Au-AgInSe 2 ) and their synthesis methods. Background technique [0002] As the most promising renewable energy, solar energy has the advantages of huge reserves, no geographical restrictions, clean and renewable. Under the trend of increasing global energy demand, the research and application of solar energy plays an important role in the long-term energy strategy. In the effective use of solar energy, the most extensive and dynamic field is photovoltaic power generation. Its working principle is to use the photovoltaic effect of semiconductors to convert solar energy into electrical energy that can be widely used by humans. The development of nano science and technology provides necessary theoretical and technical reserves for the development of new solar cells. For example, with CuInSe 2 ...
