Ultraviolet photodetectors

with a broad range of applications in fields such as environmental monitoring

biomedical imaging

advanced optical communication systems

and ultraviolet radiation measurement

present substantial research value. Wide-bandgap oxide semiconductor materials

intrinsically sensitive to the ultraviolet band

have become a focal point in ultraviolet photodetection research due to their unique detection advantages.This paper reviews the research achievements in the field of ultraviolet photodetection obtained by domestic and foreign research groups in recent years

which focus on wide-bandgap oxide semiconductor materials (ZnO

) and adopt new processes

new materials

and new structures.These achievements provide a reference for future development of new ultraviolet-sensitive materials and the fabrication of high-performance ultraviolet photodetectors.
