Ca F۲ Nanop articles: S ynthesis and Char acterizati on

It has been well-established th at alkali ear th metal (AEM) fluorides MF۲, where M = Ca, Sr or Ba, should be ver y attractive host crystals for some ap plications. These applic ations may Ba as Ln and transition metal laser activators since they pos sess a broa d optical tra nsparency re gion, moderate Raman gain coeffi cients, relatively small linear and non-linear refractive indices, and rather flat curvature of th e refractive index dispersion over a wide wavele ngth range in the near IR [۱]. The a im of the present study was to prepare nano-sized calcium fluoride (C aF۲). Nanop articles were synthesi zed by co-p recipitation method. T he synthesized nanocrystals were characterized by X-ra y diffractio n (XRD), F ourier transform infrared spectroscopy (FTIR), scanning electron mic roscopy (SE M).
