摘要

ZnTe nanocrystals were synthesized by hydrothermal method and they were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM) and micro-Raman spectroscopy. The results indicate that the ZnTe nanocrystals were crystallized in cubic zincblende structure and their morphologies and sizes are polyhedron and diversified, respectively. The Raman results show that different scattering occurred from the ZnTe nanocrystals depending different excitation wavelengths. According to theories related to band-gap and Raman scattering, the excitation wavelength-dependent Raman scattering from the ZnTe nanocrystals was analyzed.
