A facile synthesis and luminescence properties of CeF₃:Tb³⁺ via polyol method

Abstract

Sugar gourd shaped CeF 3 :Tb 3 + has been successfully synthesized by polyol method. The phase, morphology and fluorescent properties of CeF 3 :Tb 3 + were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), infrared spectroscopy (IR) and photoluminescence (PL) spectra, respectively. It can be seen that the volume changes of giethylene glycol (DEG) and H 2 O content did not affect the phase structure of CeF 3 :Tb 3 + . The emission spectrum of CeF 3 : Tb 3 + shows the characteristic emissions of Tb 3 + ion, indicating that an energy transfer from Ce 3 + to Tb 3 + occurs in CeF 3 :Tb 3 + , and the decay time of CeF 3 :Tb 3 + was not affected by the change of DEG content.
