Synthesis and optical properties of ZnAl2O4/Al2O3:Cr3+ composite materials
Main Article Content
Abstract
Zinc aluminate - alumina (ZnAl2O4/Al2O3) systems doped with Cr3+ different concentrations were synthesized by sol-gel method. The samples were characterized by X-ray diffraction (XRD), photoluminescence (PL) and photoluminescence excitation (PLE) spectra. The results showed that Cr3+ dopant concentration had a significant effect on the lattice constants of ZnAl2O4/Al2O3 composite and their luminescence characteristics.
Keywords:
Zinc aluminate – alumina composite, sol-gel, photoluminescence.
