The emission mechanism of InGaN/GaN quantum wells is greatly affected by the quantum confined Stark effect (QCSE), and the emission efficiency is significantly reduced at emission wavelengths from blue to green. In this study, we performed PL measurement by using Ag or Al coated samples to examine the effect on the blue emission from InGaN/GaN when the QCSE was reduced by using the polarity of the GaN substrate in the emission enhancement using surface plasmon resonance.
