Abstract
Nanoparticles of calcium fluoride (CaF2) doped with Erbium doped are prepared using co-precipitation technique. Preliminary characterization of the samples is carried out using PXRD, SEM and FTIR. The nanoparticles are irradiated with g-rays. Optical studies on the irradiated samples are made through absorption and luminescence measurements
