ZnO:Tm,Gd materials with high quality blue light-emitting 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: 1 D23 H4 and 1 G43 H6, the optimal heat preservation time was 3 h, the proportion of matrix and doping elements was 100: 2, and the optimal proportion of Tm and Gd was 3: 2.


ZnO:Tm,Gd Materialien mit hochwertiger Blaulichtausbeute wurden erfolgreich mittels des chemischen Ko-Präzipitation-Verfahrens hergestellt. Die Oberflächenmorphologie, die Zusammensetzung, die Kristallstruktur und die Fluoreszenz-Eigenschaften wurden mittels thermogravimetrischer und Differentialthermoanalyse sowie mittels Rasterelektronenmikroskopie, XRD und Photoluminiszenz untersucht. Die Ergebnisse zeigen, dass die niedrigste Sintertemperatur 580°C war, die optimale Sintertemperatur betrug 900°C. ZnO:Tm3+,Gd3+ hat zwei Emmissionspeaks: 1D23H4 und 1G43H6. Die optimale Wärmedauer betrug 3 Stunden, das Verhältnis zwischen Matrix und Dotierungselementen betrug 100:2 und das optimale Verhältnis zwischen Tm und Gd betrug 3:2.
