摘要
根据色度学原理计算,通过选择匹配的基色波长和功率,制备了GaN/GaAs基ITO键合白光发光二极管(LED),得到了等能白光。通过测试发现,在20mA下,电压为5.3V,此方法是制备固态照明用白光LED的有效方法之一。
The white light emitting diode was made by GaN/GaAs wafer bonded in our experiment.With this method,we obtained equal energy white light by choosing the primary colors with matched wavelength and light power through color matching calculation.The forward voltage of the diodes at the typical driving current of 20 mA was 5.3 V.This data is lower than the voltage of the ones using the tunneling junction.This method has great potential in the solid-state lighting.
