Full Textچکیده
CaF2 Nanoparticles were successfully synthesized using hydrothermal method, then this nanoparticles with polymer PVA(polyvinyl alcohol)made a good composite. The synthesized Nanoparticles were characterized by X-ray Diffraction (XRD), Transmission Electron Microscopy (TEM), scanning electron microscopy (SEM), UV-Vis spectroscopy, Photoluminescence(PL) and FTIR(Fourier Transform Infrared Spectroscopy). The crystallite size estimated using Scherer’s formula was found to be in the range 23–32nm. TEM images reveal the growth of agglomerated Nanoparticles with average size of 50-80 nm. Optical absorption spectrum shows a strong absorption edge at 310nm. The PL emission spectrum showed two prominent emission peaks at 390 and 790nm when excited at 394.4 nm.
