Abstract
A light-responsive LED (Light Emitting Diode) based on a GaN/CsPbBrIheterojunction, a preparation method and an application thereof are provided. The light-responsive LED consists of a GaN base layer on a sapphire substrate, an all-inorganic perovskite CsPbBrIfilm, an indium electrode and a carbon electrode, forming an In/GaN/CsPbBrI/C structure, wherein: in the CsPbBrIfilm, 0<x<3; the all-inorganic perovskite CsPbBrIfilm and the indium electrode are arranged on the GaN base layer in parallel; and the carbon electrode is arranged on the all-inorganic perovskite CsPbBrIfilm. The CsPbBrIfilm is prepared through a low-temperature anti-solvent method. The prepared LED device is able to realize integration of self-powered visible detection and visible luminescence, and able to work as a transmitting terminal or a receiving terminal in visible light wireless communication, which solves a difficult problem of backward communication in visible light wireless communication technology.
