The study utilizes transmission electron microscopy (TEM) and UV-visible absorption spectroscopy to analyze the size and band gap of the nanocrystallites, revealing sizes around 2.3 nm and a band gap increase to approximately 2.7 eV due to the reduction in crystallite size.

在这项研究中，在CZT上进行了原位透射电子显微镜（TEM）纳米压痕，发现在41.9μN的峰值载荷下没有发生脆性断裂，相当于1.75 GPa的应力。 原位诱导的新纳米结构观察到TEM纳米压痕，包括单晶，滑带，堆垛层错，超晶格，新的四方相和莫尔条纹。 新的四方相是由（11 ）平面中沿 [ 2 ]方向滑动的部分Cd和Te原子形成的，通过从头算就可以说明这一点。 它属于四方晶体体系，沿X和Y轴的晶格距离分别为0.382和0.376 nm。 我们的发现为软脆性固体的形变诱导相变提供 …

atomic resolution imaging using an analytical JEOL 2011 TEM fitted with a LaB6 filament were used to determine the CdS nanocrystal’s composition, crystallographic structure, defect structures and size with a view to understanding how these affect the stability, band gap energy and luminescence properties.

2011年9月9日 · This work presents the results of an investigation of cadmium sulphide with various characterisation techniques such as TEM- Cathodoluminescence, SEM, XRD, PL and optical transmittance. A model based on a convolution method is proposed to predict CL signal emission. It was assumed that the CL can originate from electron and X-ray sources.
