As one of the emerging ultrawide-bandgap semiconductors, gallium oxide(Ga_2O_3) exhibits unique advantages over other wide-bandgap semiconductors, especially in developing high-performance solar-blind photodetectors. This paper comprehensively reviews the latest progresses of solar-blind photodetectors based on Ga_2O_3 materials in various forms of bulk single crystal, epitaxial films, nanostructures, and their ternary alloys.The basic working principles of photodetectors and the fundamental properties and synthesis of Ga_2O_3, as well as device processing developments, have been briefly summarized. A special focus is to address the physical mechanism for commonly observed huge photoconductive gains. Benefitting from the rapid development in material epitaxy and device processes, Ga_2O_3-based solar-blind detectors represent to date one of the most prospective solutions for UV detection technology towards versatile applications. 关键词：Solar-blind photodetectors ultrawide-bandgap SEMICONDUCTORS wide-bandgap SEMICONDUCTORS
