利用溶胶-凝胶法合成了Er2O3-Yb2O3-SiO2纳米二氧化硅(SiO2)粉。Er3+和Yb3+直接加入有机酸催化的TEOS反应溶液中,凝胶后经过700~900℃,得到Er3+-Yb3+共掺纳米SiO2粉。样品经过红外光谱、XRD、TEM等分析,结果表明,纳米粉的粒径受有机酸比例和处理温度的影响。在室温PL谱上,样品可观察到较强的1530nm荧光,同时镱的引入对掺铒SiO2纳米粉在1.54μm的荧光发射有增强作用。 Er2O3-Yb2O3-SiO2 nanosilica (SiO2) powders were synthesized by sol-gel method. Er3 + and Yb3 + were directly added to the organic acid catalyzed TEOS reaction solution, and the gel was passed through 700-900 ° C to obtain Er3 + -Yb3 + co-doped nano-SiO2 powder. The samples were analyzed by infrared spectroscopy, XRD and TEM. The results showed that the particle size of nano-powders was affected by the proportion of organic acids and the treatment temperature. The PL spectrum at room temperature, the sample can be observed strong 1530nm fluorescence, while the introduction of ytterbium erbium-doped SiO2 nanopowder 1.54μm fluorescence emission enhancement.
