InGaN/GaN multiple quantum well (MQW) structure was prepared MOVPE and characterized by fine XRD measurements. Suitability for scintillator application including a unique measurement of wavelength-resolved scintillation response under nanosecond pulse soft x-ray source in extended dynamical and time scaleswas demonstrated. The photoluminescent and radioluminescent spectra were measured. the ratio of the intensity of quantum well (QW) exciton luminescence to the intensity of the yellow luminescence (YL) band IQW/IYL depends strongly on the type and intensity of excitation.
