Abstract EN
A new synthetic chemical coprecipitation route for the preparation of well-crystallized size controlled nano- and microcrystalline cubes of CaF2 is reported.
Crystalline cubes in the range of 2 μm–20 nm could be synthesized and their sizes were controlled by varying the solvent : cosolvent ratio.
The as-synthesized CaF2 nanocubes were characterized by different techniques.
Photoluminescence (PL) emission spectrum of CaF2 nanocrystalline powder showed strong emission band at 415 nm.
Moreover, the effect of Eu as a dopant on the emission spectrum of CaF2 was investigated.
This dopant was found to get incorporated in its Eu2+ and Eu3+ forms.
The as-produced nanocubes were exposed to UV irradiation and the corresponding PL emission was studied.
Excellent results are obtained, where CaF2:Eu nanocubes were found to be highly sensitive and might be suitable for esteeming the doses of UV irradiation using the PL technique.
