Abstract

ZnO:Tm,Gdmaterials with high quality blue light emissions were successfully prepared using the chemical co-precipitation method. The surface morphology, composition, crystal structure and fluorescence properties were investigated using the thermogravimetric analysis/differential thermal analysis (TG/DTA), scanning electronic microscopy (SEM), X-ray diffraction (XRD), and photoluminescence (PL). The results showed that the lowest sintering temperature was 580°C; the optimal sintering temperature was 900°C;ZnO:Tm3+,Gd3+had two emission peaks:1D2→3H4and1G4→3H6; the optimal heat preservation time was 3 h; the proportion of matrix and doping elements was 100:2; and the optimal proportion ofTmandGdwas 3:2.
