| 摘 要： | 测量以GaAs为衬底的Zn1-xCdxSe／ZnSe应变层多量子阱在不同温度下（18～300K）的光伏谱，研究Zn1-xCdxSe／ZnSe多量子阱的光伏效应和带间激子跃迁，实验结果表明，Zn1-xCdxSe／ZnSe量子阱具有显著的量子限制效应，从18K直至室温，都能观测到清晰的激子跃迁峰，说明Zn1-xCdxSe／ZnSe是制作室温下工作的蓝绿激光器等发光器件的合适材料。

| Abstract: | The photovohage spectra of Zn1-xCdxSe/ZnSe multiple quantum wells on GaAs substrates at temperatures from 18K to 300K were measured. The photovohaic effects and exciton transitions of Zn1-xCdxSe/ZnSe multiple quantum wells were studied. The experimental results show that there is marked quantum confined effect in Zn1-xCdxSe/ZnSe quantum well and the exciton transitions can be observed from 18 K to room temperature,which indicates that Zn1-xCdxSe/ZnSe quantum well could be a kind of suitable materials for bluegreen photonic devices. |
