[Synthesis and fluorescence of KznF3 : Ce3+, Tb3+ nanoparticles].

Phosphors of KZnF3 : Ce3+, KZnF3 : Tb3+ and KZnF3 : Ce3+, Tb3+ nanoparticles were synthesized in a cetyltrimethylammonium bromide (CTAB)/2-octanol/water microemulsion system. X-ray diffraction (XRD) pattern was used to identify the formation of KZnF3 phase without detectable impurity. Environment scanning electron microscopy (ESEM) image showed that the average sizes of the KZnF3 : Ce3+ , Tb3+ nanocrystals were 30 nm in diameter.
