(F)=1:1:4 is the best. The up-conversion luminescence of the samples with this ratio is the strongest before and after high temperature treatment. After high temperature treatment
the intensity of visible light emission increases significantly. XRD results show that Tm

. After high temperature treatment
part of -phase and amorphous phase turn to -phase
which results in the crystallinity improving. HRTEM image also shows that - and -phase coexist in the sample. The excitation of 980 nm laser hardly has effect on the paramagnetism of the samples
but the changing magnetic field has negative effect on the up-conversion luminescence of the samples.
