Abstract

In order to realize preferable white light-emitting diodes with high color rendering index and optimized luminous efficiency,white InGaN/GaN multi-quantum-well dual-wavelength light-emitting diodes(LEDs) were grown on(0001)-oriented sapphire substrates by metal-organic chemical vapor deposition(MOCVD).Photoluminescence and electroluminescence properties of dual-wavelength LEDs with different In content were also studied.The experimental results indicated that In component plays a critical role on stability for electroluminescence spectrum and luminous efficiency of the dual-wavelength LED structures.In addition,YAG∶Ce phosphor-converted white light emission with high color rendering index was achieved using dual-blue emitting active regions.
