Eu3+-doped sub-10 nm LaOCl nanocrystals with 43% photoluminescence quantum yield were prepared by solvothermal synthesis from hydrated rare-earth chlorides. As-obtained nanocrystals are nearly spherical, monodisperse and stable as colloidal dispersions. These combined features should intensify the interest for nanocrystalline rare-earth oxyhalides and their optical properties.
通过水合稀土氯化物的溶剂热合成法制备了光致发光量子产率为43%的Eu3+掺杂亚10纳米LaOCl纳米晶体。所获得的纳米晶体近乎球形，单分散且作为胶体分散体稳定。这些综合特性应会增强人们对纳米晶稀土卤氧化物及其光学性质的兴趣。
