Two wide bands centred at 644 and 695 nm have been observed at T = 10 K. A detailed analysis of the spectra obtained by varying the excitation intensity and temperature resulted in the identification of the levels involved. A simple model is proposed to account for the observed data.EnglishPhotoluminescenceSemiconducting gallium compoundsSpectrum analysisThermoanalysisExcitation intensityWavelengthsSingle crystalsArticle10.1080/095008301100938851362-3036
