中文摘要：
采用微乳液法制备了LaF3：Er,Yb纳米颗粒,在有机-无机杂化材料中有良好的溶解性,掺杂质量比可达到50%。通过TEM观察到纳米颗粒的粒径为610 nm;XRD的测试结果表明材料中形成了LaF3六方晶体结构;荧光发射谱的测试表明纳米颗粒的荧光半峰全宽为79 nm;通过时间相关单光子计数法测得铒离子4I13/2能级的寿命为100μs。结合半导体工艺,制备了嵌入条形结构的平面光波导放大器,在信号光（1 550nm）功率为0.2 mW,泵浦光（980 nm）功率为188 mW的条件下,在1.9 cm的样品上得到了3.2 dB的相对增益;同时分析了散射损耗随颗粒大小的变化关系。
英文摘要：
In this paper,oleic modified LaF3∶Er,Yb nanoparticle（NP） is prepared by micro-emulsion method.This NP has a excellent solubility in organic solvent and NP’s doping concentration can reach as high as 50%.Observed by TEM’s photograph,most of NP’s diameter is about 610 nm;there is hexagonal LaF3 structure in the materials by X-ray diffraction pattern;NP shows potential high gain bandwidth because full width at half maximum（FWHM） is 79 nm which is bigger than inorganic matrix erbium doped waveguide amplifier（EDWA）;100 μs lifetime of the 4I13/2 energy level is also measured.At last,a planar waveguide is fabricated by semiconductor process,a relative gain of 3.2 dB can be got in a 1.9 cm length sample with 1 mW signal power.The relationship between gain and nanopaticle diameter is also analyzed.
