Abstract
ZnO nanoparticles grown on highly porous silica with spherical and rod-like morphology were investigated by radioluminescence and photoluminescence measurements to assess the influence of intrinsic defectiveness on the optical properties. Spectroscopic analysis of ZnO/SiO2 systems unveils defect-related luminescence and a very weak excitonic emission. The samples display peculiar optical properties with unlike intensity and energy emissions, disclosing the occurrence of inequivalent defect centers in ZnO nanoparticles supported onto silica with different morphology.
