Abstract

A series of BaGdF5:x% Tb3+,y% Sm3+ phosphors are synthesized by a hydrothermal method, taking the form of irregular nanospheres with average sizes of about 20 nm. An energy transfer from Tb3+ to Sm3+ is observed in the BaGdF5:Tb3+,Sm3+ system, which is justified by the luminescence spectra. Simultaneously, a resonance-type energy transfer from Tb3+ to Sm3+ is demonstrated to occur via the dipole–dipole interaction, for which the critical distance (RTb–Sm) is calculated to be 13.49 Å. Furthermore, based on the rare earth concentrations and excitation wavelengths, multiple (white, orange red, green and green yellow) emissions are obtained by Sm3+ ion co-activated BaGdF5:Tb3+ phosphors, which could make them good candidates to be used as full-color phosphors for nUV-LED. More importantly, the obtained samples also exhibit paramagnetic properties at room temperature and low temperature.
