Abstract
We have investigated the photon-generated carrier dynamics of InGaN/GaN nanocolumns whose emission wavelength is in the orange to red region, focusing on the changes in the photoluminescence spectra, emission efficiency and relaxation curves. We have explained these changes by considering the filling of non-radiative centers, emission from localized states, the processes above the mobility-edge density and other non-radiative processes.
