In this paper, InSe nanosheets were synthesized by a ball milling method, and photoelectrochemical-type photodetectors (PEC PDs) based on the ball milling InSe (M-InSe) were fabricated using simulated seawater as the electrolyte. M-InSe nanosheets show good absorption in the visible region of 450-600 nm. The M-InSe PEC PDs display a good self-powered photoresponse under 525 nm irradiation, including a high responsivity of 0.8 mA/W, fast response time of 28/300 ms, and good stability. Furthermore, the InSe PEC PDs successfully demonstrated prototype application in wireless underwater optical communication and optical imaging. These results demonstrate that M-InSe holds good application prospects in underwater optoelectronic devices.
在本文中，通过球磨法合成了InSe纳米片，并以模拟海水为电解质制备了基于球磨InSe（M-InSe）的光电化学型光电探测器（PEC PDs）。M-InSe纳米片在450-600nm的可见光区域表现出良好的吸收。M-InSe PEC PDs在525nm光照下显示出良好的自供电光响应，包括0.8 mA/W的高响应度、28/300 ms的快速响应时间和良好的稳定性。此外，InSe PEC PDs成功地展示了在无线水下光通信和光学成像中的原型应用。这些结果表明，M-InSe在水下光电器件中具有良好的应用前景。
