چکیده: Abstract
We used CaCl2 and NH4F from Merck Company for synthesis CaF2 NPs. We synthesized CaF2 Nanoparticales
(NPs) using Co-precipitation and hydrothermal method successfully. The synthesized NPs were characterized by X-ray
diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, Transmission Electron Microscopy (TEM), Scanning
Electron Microscopy (SEM), UV-Vis spectroscopy and Photoluminescence (PL) techniques. The XRD results indicated
the formation of CaF2 NPs with Cubic phase and the crystallite size is estimated using Scherrer’s to be in the range
20–27nm for the powders prepared by co-precipitation and 20–31nm for hydrothermal methods, respectively. TEM
images revealed the grains have almost spherical shape. Optical absorption spectrum shows a strong absorption edge
at about 300nm.
