The excitonic properties in two (Ill)B-grown lno.lsGao.ssAs/GaAs multiple quantum well p-i-n diodes are investigated by thermally-detected optical absorption and electroreflectance measurements. The lineshape of the electroreflectance spectra is analysed by means of a multilayer model enabling the e
