Description

technical field

[0001] The invention relates to a preparation method of a bismuth sulfide nanorod crystal material, in particular to a method for preparing bismuth sulfide nanorods under low temperature and normal pressure conditions by using a composite nitrate solvent synthesis method. Background technique

[0002] Nano metal sulfide crystal materials have semiconducting, luminescent and optoelectronic properties, and can be used in sensors, biomarkers, electronic devices, light emitting devices and optoelectronic devices. In the existing method for synthesizing sulfide, the composite solvothermal method (patent: 200510103028.9 and Langurir, 2006, 22, 7364), adopts hydroxide, fatty acid and multiple organic polar solvents to mix as synthetic solvent, with metal salt and Sodium sulfide is the raw material for synthesis. First prepare the reaction precursor, such as mixing a certain amount of sodium hydroxide with a small amount of oleic acid, then adding ethanol solution an...
