摘要
The effect of different barriers between green and blue light regions in dual wavelength light emitting diodes was studied.Compared with a traditional sample,electroluminescence and photoluminescence spectra of the newly designed samples showed peak intensity improvements and smaller blue-shifts with increasing injection current level,and the bottom quantum-wells light emitting is enhanced.All these phenomena can be ascribed to reduced barrier thickness and indium doping in the quantum-barrier influencing electric fields and more holes injecting into the bottom QWs.
