摘要

采用扩散限制生长技术，在硼硅酸盐玻璃基体中生长出了具有三种阳离子的四系CdS1−x−ySexTey纳米晶体样品。它们的拉曼光谱证实了CdS1−x−ySexTey声子光谱的三模组成行为。实验分析了含x≈y纳米晶体样品中LO声子频率的组分依赖性。

Raman Spectra of Quaternary CdS1−x−ySexTey Nanocrystals Embedded in Borosilicate Glass

A series of samples with quaternary CdS1−x−ySexTey nanocrystals with cations of three types distributed over nanocrystal lattice sites were grown in a borosilicate glass matrix by the diffusion-limited growth technique. Their Raman spectra confirm the three-mode compositional behaviour of CdS1−x−ySexTey phonon spectra. The compositional dependence of the LO phonon frequencies is analysed experimentally for a series of samples containing nanocrystals with x≈y.
