## Abstract Excitation densityβdependent microphotoluminescence measurements were performed on a green light (515βnm) emitting InGaN/GaN multiquantum well sample of low threading dislocation density (5βΓβ10^7^βcm^β2^). For the observed structure we find a different shape of the local internal quant
