我们使用高分辨率透射电子显微镜来评估通过阳离子交换形成的PbTelCdTe和PbSelCdSe核壳纳米粒子。我们发现,核和壳具有相同的晶体取向,并且核的形状是由各向异性生长机制。
We use high-resolution transmission electron microscopy to assess the formation of PbTelCdTe and PbSelCdSe corelshell nanoparticles by cationic exchange. We find that core and shell have the same crystallographic orientation, and that the core shape is governed by an anisotropic growth mechanism.
