| Abstract: | The correlation between the excitation and fluorescence polarizations of the 4T2 → 4A2 broadband luminescence is investigated. The behaviour of the emission with the wavelength is also studied when modulating the light excitation either in intensity or in polarization. The results can be explained assuming that the broadband arise from different relaxed levels. |
