Comparison Study of High-Temperature Spontaneous Emission Quantum Efficiency of Commercial LED Materials

The spontaneous emission quantum efficiency (QE) of InGaN/GaN MQWs with different wavelengths was studied using photoluminescence (PL) spectroscopy. The QE was calculated from the power-law relation linking the integrated PL and the excitation pumping power.
