In addition, the photoelectric response performance of the ultraviolet photoelectric detector ofthe invention is excellent.

Description

technical field [0001] The invention relates to the field of photodetectors, in particular to a ZnO nanogrid-based ultraviolet photodetector and a preparation method thereof. Background technique [0002] With the rapid development of modern industry, greenhouse gases have caused serious damage to the ozone layer, the ozone layer has become thinner, and even some holes have appeared in the ozone layer. A thinning or hole in the ozone layer leads to an increase in the amount of ultraviolet light hitting the Earth's surface. Excessive ultraviolet rays are extremely harmful to life on earth. Especially for humans, excessive ultraviolet doses can easily burn the skin and even induce serious diseases such as skin cancer. Therefore, it is very important to strengthen the monitoring of outdoor ultraviolet rays. ZnO is a kind of non-toxic, excellent biocompatibility, abundant raw material II-VI wide bandgap semiconductor material, and also an emerging ultraviolet optoelectronic m...
