| Abstract: | In this paper, CeF3:Tb3+ nanodiskettes were prepared by the hydrothermal microemulsion method for the first time and the photoluminescent properties
of CeF3:Tb3+ nanodiskettes were investigated. The structural properties of CeF3:Tb3+ nanodiskettes were characterized by X-ray diffractions and transmission electron microscopy. The photoluminescent properties
of CeF3:Tb3+ with different Tb3+ ions concentration were investigated by excitation spectra, emission spectra and lifetime measurement. The energy transfer
processes from Ce3+ to Tb3+ and from Tb3+ to Tb3+ were analyzed and discussed. Results show that CeF3:Tb3+ nanodiskettes may be applied as phosphors for high resolution displaying.
