Highly luminescent CdSe/CdS core-shell nanocrystals have been assembled on indium tin oxide (ITO) coated glass substrates using a wet synthesis route. The physical properties of the quantum dots (QD) have been investigated using X-ray diffraction, transmission electron microscopy and optical absorption spectroscopy techniques. These quantum dots showed a strong enhancement in the near band edge absorption. The in situ luminescence behavior has been interpreted in the light of the quantum confinement effect and induced strain in the core-shell structure.
通过湿合成路线,在氧化铟锡(ITO)涂层玻璃基板上组装了高发光的CdSe/CdS核壳纳米晶体。使用X射线衍射、透射电子显微镜和光吸收光谱技术研究了量子点(QD)的物理性质。这些量子点在近带边吸收方面表现出强烈增强。根据量子限制效应和核壳结构中的诱导应变对原位发光行为进行了解释。
