| Abstract: | Fluorescent and phosphorescent semiconductor nanoparticles, metal-doped semiconductor nanoparticles, metal nanoparticles or nanoclusters, carbon dots or graphene dots, silicon dots were introduced. The photophysical and photochemical processes of the luminescent nanomaterials were explained. Finally, the general mechanisms of luminescent quenching or enhancement aimed at chemical sensors were reviewed. |
