制备了油酸修饰的LaF 3：Er，Yb纳米晶。的OA封端的纳米晶体具有近球形的形状，平均直径为7 nm，并显示出良好的分散在常见的有机溶剂和PMMA基质。可以获得在甲苯中的0.25 g ml−1透明胶体溶液。所得的纳米晶体-聚合物杂化材料在980 nm激发时在1550 nm电信窗口附近表现出强发射，并且是用于聚合物基光波导放大器的有前途的材料。
Oleic acid (OA)-modified LaF3 : Er,Yb nanocrystals (NCs) have been prepared and investigated. The OA-capped nanocrystals have a nearly spherical shape with a mean diameter of 7 nm and show excellent dispersibility in common organic solvents and a PMMA matrix. A 0.25 g ml−1 transparent colloidal solution in toluene can be obtained. The resulting nanocrystal–polymer hybrid materials exhibit strong emission around the 1550 nm telecommunication window when excited at 980 nm and are promising materials for polymer-based optical waveguide amplifiers.
