Temperature and excitation power behaviour of the emission from low dimensional structures can provide important information about localisation effects, strain and electric field distribution. Usually it is difficult to separate the contribution of the particular effect on the observed photoluminescence. In order to understand the influence of those effects photoluminescence measurements in the temperature range 4.2-300K on GaN/AlGaN quantum wells (QW) of different width were performed.
