“…However, for the YBCO doped with 0.1% SiO 2 , the PL spectrum at 77 K is composed of three bands located approximately at 1.44, 1.88, and 2.30 eV. This new band located at 1.44 eV is a characteristic of the transitions between holes in the oxygen-derived 3d 10 and 3d 9 valence bands [13]. This band disappears when the temperature is increased to 97 K. The vibration density in the crystal and the diffusion rates of the carriers by the defects increase as the temperature varies, and therefore, the evolution of PL intensity with the temperature can be attributed to the exchange of the photo-carriers between the different excited levels and the interaction of the photo-carriers with vibration modes and the defects in the crystal.…”
