Facile-Controlled Epitaxial Growth Direction of Heterogeneous CoreShell Structured NaLnF4 Nanocrystals through Traditional Methods

Abstract EN

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.
