Title:
METHOD FOR PREPARING CDS NANORODS
Document Type and Number:
WIPO Patent Application WO/2019/000477
Kind Code:
A1
Abstract:
A method for preparing CdS nanorods, the preparation method comprising the following steps: S1, mixing cadmium acetate with trioctylphosphine, stirring and heating under a nitrogen atmosphere, and then injecting a sulfur solution into the mixture so as to carry out a reaction; S2, cooling the solution to room temperature after the reaction, adding anhydrous methanol so as to precipitate CdS nanorods, and washing the CdS nanorods by using anhydrous ethanol; S3, performing wet processing on a film of CdS nanorods by using CdCl2. By means of performing CdCl2 wet processing on the film of CdS nanorods, the crystallinity of the film is improved, defective state density is reduced, short circuit current density is greatly improved, and the service life of a battery is extended.
