preparation and characterization of caf2:ce3+ nanoparticles with spectroscopic studies

in this research calcium fluoride nanoparticles and its different amount of cerium ion dopant (5%and 10%) were prepared. the mentioned nanoparticle were studied by fourier transform infrared spectroscopy (ftir) , x-ray diffraction (xrd), absorption and photoluminescence spectra (pl) and scanning electron microscopy (sem). the xrd patterns indicate a typical cubic fluorite structure and no other impurities. sem results show the synthesized particles having uniform grain size. many absorption peaks and bands are present in the absorption spectra, corresponding to the rich energy levels of cerium ion.
