TiO 2 as Trap Sensitizer for Enhanced Persistent Luminescence in ZnGa 2 O 4 :Cr 3 + Nanoparticles

ABSTRACT Enhancing the charging efficiency of persistent luminescence materials remains a key challenge for their practical implementation. Here, we report a hybrid strategy based on coupling ZnGa 2 O 4 :Cr 3 + nanoparticles with TiO 2 through a porous SiO 2 interlayer to promote...
