Abstract: We report on the luminescence spectra related to Ti impurity in 6H-SiC. The spectra depend strongly on the polarization. There are three families of PL lines. Phonon structure is observed containing both broad and sharp replicas. When the temperature increases extra lines appear at high energy. Time-resolved PL reveals a 0.1 ms long lifetime at 2 K.
