The role of luminescence self-absorption in photocatalytic properties of self-assembled ZnS nanocrystals
In this work, we used a template-free method to synthesize zinc sulfide (ZnS) materials. The photocatalytic performances of the samples were evaluated, and the physical natures of the ZnS nanocrystals were determined by photoluminescence (PL). Interestingly, the temperature-dependent PL variations o...
