This study supplies new in 806 hybrid nanoparticles were meticulously studied. This study gives new insights in to the sights into the mechanistic understanding of UV upconversion luminescence in hybrid mechanistic understanding of UV upconversion luminescence in hybrid nanoparticles and nanoparticles and enables new opportunities for these nanomaterials within a broad range of enables new possibilities for these nanomaterials inside a broad range of applications. applications.2 ofScheme 1.
