    • Dependence of the photoluminescence of Tl2InGaS4 layered crystal on temperature and excitation intensity 

      Gasanly, N. M.; Serpengüzel, A.; Gürlü, O.; Aydınlı, A.; Yılmaz, I. (Pergamon Press, 1998)
      The emission band spectra of Tl2InGaS4 layered crystals were investigated in the 10-120 K temperature range and in the 540-860 nm wavelength range using photoluminescence (PL). The peak energy position of the emission band ...
    • Low-temperature phase transitions in TlGaS2 layer crystals 

      Aydinli, A.; Ellialtioǧlu, R.; Allakhverdiev, K. R.; Ellialtioǧlu, S.; Gasanly, N. M. (Pergamon Press, 1993)
      Polarized Raman scattering spectra of TlGaS2 layer crystals have been studied for the first time as a function of temperature between 8.5 and 295 K. No evidence for a soft mode behaviour has been found. The anomalies ...
    • Low-temperature photoluminescence spectra of TlInxGa1-xS2 layer mixed crystals 

      Allakhverdiev, K. R.; Gasanly, N. M.; Aydinli, A. (Pergamon Press, 1995)
      Low-temperature photoluminescence spectra of TlInS2, TlIn0.95Ga0.05S2 and TlIn0.8Ga0.2S2 layer crystals were studied in the temperature range 14-220 K. The temperature dependencies of bands 2.374 eV (A), 2.570 eV (E) and ...
    • Low-temperature visible photoluminescence spectra of TlGaSe2 layered crystal 

      Gasanly, N. M.; Serpengüzel, A.; Aydınlı, A.; Baten, S. M. A. (Elsevier Science Publishers B.V., Amsterdam, Netherlands, 2000)
      The photoluminescence (PL) spectra of TlGaSe2 layered single crystals were investigated in the 8.5-35 K temperature. 0.2-15.2 W cm-2 excitation laser intensity, and in the 600-700 nm wavelength range. The PL spectrum has ...
    • Radiative donor-acceptor pair recombination in TlInS2 single crystals 

      Aydınlı, A.; Gasanly, N. M.; Yılmaz, I.; Serpengüzel, A. (Institute of Physics Publishing, 1999)
      Photoluminescence (PL) spectra of TlInS2 layered single crystals were investigated in the 500-860 nm wavelength region and in the 11.5-100 K temperature range. We observed two PL bands centred at 515 nm (2.41 eV, A band) ...
    • Temperature-and excitation intensity-dependent photoluminescence in TlInSeS single crystals 

      Gasanly, N. M.; Aydinli, A.; Yuksek, N. S. (American Institute of Physics, 2002)
      Photoluminescence (PL) spectra of TlInSeS layered single crystals were investigated in the wavelength region 460-800 nm and in the temperature range 10-65 K. We observed one wide PL band centred at 584 nm (2.122 eV) at T ...
