| Abstract | 采用高温固相法制备了Li~+、Bi~(3+)掺杂Lu_2O_3∶Ho~(3+),Yb~(3+)粉体。用X射线衍射仪分析了合成粉体的微结构,用场发射扫描电子显微镜观测了样品的形貌及尺寸,用紫外可见近红外荧光光谱仪分析了合成粉体的上转换发射光谱以及能级寿命。结果表明:Li~+、Bi~(3+)掺杂的Lu_2O_3∶Ho~(3+),Yb~(3+)粉体,仍然保持Lu_2O_3立方相结构。Li~+或Bi~(3+)掺杂后,合成粉体的分散性更好,颗粒更均匀,且更加接近球形,Li~+掺杂后粉体颗粒尺寸明显增加。用980 nm激发,4%Li~+或1.5%Bi~(3+)掺杂后,合成粉体中Ho~(3+)的绿光光强分别提高了约3.9倍、2.8倍。随着Li~+浓度的增加,合成粉体中Ho~(3+)的~5S_2能级寿命先增加后减小;随着Bi~(3+)浓度的增加,合成粉体中Ho~(3+)的~5S_2能级寿命逐渐减小。 |
| Other Abstract | Li^+ ,Bi^(3+) doped Lu_2 O_3 ∶ Ho^(3 +) ,Yb^(3+) powders were prepared by high temperature solid state method. The microstructure of the synthesized powder was analyzed by X-ray diffractometer. The morphology and size of the sample were observed by field emission scanning electron microscopy. The up conversion emission spectra and energy level lifetime of the synthesized powders were analyzed by UV-Vis near-infrared fluorescence spectrometer. The results show that Li + ,Bi3 + doped Lu2O3 ∶ Ho3 + ,Yb3 + powders still maintain the Lu2O3 cubic phase structure. After Li + or Bi3 + doped, the dispersion of the synthesized powders is better, the particles are more uniform and closer to the sphere, and the particle size of Li + doped powders increases obviously. Under the excitation of 980 nm,the green light intensity of Ho3 + in the 4% Li + or 1. 5% Bi3 + doped powders is increased by about 3. 9 times and 2. 8 times, respectively. With the increase of Li + concentration, the 5 S2 energy level lifetime of Ho3 + in the synthetic powders increase first and then decrease, while with the increase of Bi3 + concentration, the energy level lifetime of synthetic powders are gradually shortened. |
