In previous studies, most photocatalytic dye degradation was conducted by using broad-angular emission lamps, light-emitting diodes, and conventional lasers. However, these types of light sources could be restricted by some disadvantages, such as weak intensity or high directionality. Unlike traditional lasers, random lasers obviate the need for the cavity. The advantage of broad-angular emission lights and the feature of laser-level intensity make random lasers a promising light source for many potential applications. In this study, an ultraviolet random laser (UVRL) derived from zinc oxide (ZnO) was used in the photocatalytic dye degradation experiment. It is found that the degradation efficiency of the UVRL is much better than that of conventional lasers and ultraviolet light-emitting diodes. The success of applying random laser systems in the photocatalytic reaction is expected to expand the applications of random lasers. (c) 2023 Author(s).
