Photoluminescent properties of CeF_3:Tb~(3+) nanodiskettes prepared by hydrothermal microemulsion

摘要

In this paper, CeF_3:Tb~(3+) nanodiskettes were prepared by the hydrothermal microemulsion method for the first time and the photoluminescent properties of CeF_3:Tb~(3+) nanodiskettes were investigated. The structural properties of CeF_3:Tb~(3+) nanodiskettes were characterized by X-ray diffractions and transmission electron microscopy. The photoluminescent properties of CeF_3:Tb~(3+) with different Tb~(3+) ions concentration were investigated by excitation spectra, emission spectra and lifetime measurement. The energy transfer processes from Ce~(3+) to Tb~(3+) and from Tb~(3+) to Tb~(3+) were analyzed and discussed. Results show that CeF_3:Tb~(3+) nanodiskettes may be applied as phosphors for high resolution displaying.
