Abstract

Mn2+ doped CaAl2O4 nanoparticles were prepared by the solid state reaction method –the slurry in water approach. The crystal structures determined by XRD were monoclinic. Photoluminescence emission investigation at 465 nm excitation showed blue-green emission with emission color been doping-concentration dependent. Photoluminescence emission intensity decreased at twice doping ratio but increased at triple doping concentration. Crystal size of the nanoparticles decreased with temperature from 40.17 nm to 20.06 nm.
