OPTICAL DETECTOR AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/153698
Kind Code:
A1
Abstract:
Provided in the present invention is an optical detector, comprising a working electrode, a counter electrode, and an electrolytic solution provided between the working electrode and the counter electrode, the working electrode comprising a conductive substrate and a semiconductor layer provided on the conductive substrate, and the material of the semiconductor layer comprising two-dimensional tellurium nanosheets. The optical detector provided in the present invention has good performance. Further provided in the present invention is a manufacturing method for an optical detector, comprising the following steps: providing a tellurium raw material, and exfoliating the tellurium raw material with a liquid phase exfoliation method to obtain two-dimensional tellurium nanosheets; dispersing the two-dimensional tellurium nanosheets into a solvent to form a two-dimensional tellurium nanosheet dispersion, uniformly coating the two-dimensional tellurium nanosheet dispersion onto a conductive substrate, and obtaining a working electrode after drying; and providing a counter electrode, filling an electrolytic solution between the working electrode and the counter electrode, and obtaining an optical detector after encapsulation. The manufacturing method provided in the present invention is simple and easy to operate.
