• GaN film
• yellow luminescence
• absorption-normalized photoluminescence excitation spectroscopy

A new spectroscopy-absorption-normalized photoluminescence excitation spectroscopy is proposed and used to study yellow emission of undoped GaN. The resonant absorptive peak position of the initial state responsible for the yellow luminescence has been measured directly in experiment for the first time to our knowledge. Therefore, the emitting model of the yellow luminescence, which was controversial for long time, has been determined.
