<title>GaInN/GaN multiple quantum wells green LEDs</title>

Abstract

The high-efficient blue, green light-emitting diodes (LEDs) using GaInN/GaN multiple quantum wells (MQW) have been successfully developed. The peak wavelength of MQW blue and green LEDs are approximately 460nm and 520nm, respectively. The full width at half-maximum of the MQW blue LEDs is 40nm at a forward current of 20mA which is much narrower than 70nm of the conventional blue LEDs. The degrees of shift in peak wavelength of the MQW blue and green LEDs are less than 5nm in the current ranging from 5mA to 50mA.
