Abstract (in Japanese) (See Japanese page) 
(in English) We analyzed the IQE of whole-composition-range AlGaN multi-quantum wells (MQWs) on AlGaN with various dislocation densities by excitation density dependent PL measurement. IQE with an excess carrier density of 1×1018 cm-3 changes from 4 to 64% when the dislocation density changes from 6×109 to 2×108 cm-2. This trend is almost the same for DUV/UV MQWs with emission wavelength ranging from 230 to 350 nm.
