Fabrication of nanoscale materials with desirable morphology and surface properties becomes more urgent when constructing hybrid nanocrystals with multiple functionalities. Here, we report a facile measure to control the outer layer growth direction combining with coprecipitation and thermal decomposition method for constructing a series of heterogeneous core/shell structured NaLnF₄ nanocrystals, involving NaYF₄ and NaNdF₄ material. Our investigations suggest that it is feasible to control over the outer layer growth orientation by combining the two traditional methods.

传统方法制备的核/壳结构NaLnF4纳米晶的容易控制的外延生长方向

当构建具有多种功能的杂化纳米晶体时，具有所需形态和表面性质的纳米级材料的制造变得更加紧迫。在这里，我们报告了一种易于控制的措施，结合共沉淀和热分解方法来控制外层的生长方向，以构建一系列由NaYF ₄和NaNdF ₄材料组成的核/壳结构异质NaLnF ₄纳米晶体系列。我们的研究表明，结合两种传统方法来控制外层的生长方向是可行的。
