Photoluminescence (PL) spectra of InS were investigated in the wavelength region 477.5-860 nm and in the temperature range 8.5-293 K. We observed three PL bands centered at 605 nm (A-band), 626 nm (B-band) and 820 nm (C-band). The A- and B-bands are due to radiative transitions hom the donor level at 0.01 eV below the bottom of the conduction band to the valence band and from the donor level at 0.06 eV below the bottom of the conduction band to the acceptor level 0.12 eV above the top of the valence band, respectively. The proposed energy-level scheme allows us to interpret the recombination processes in InS single crystals. (C) 1997. Elsevier Science Ltd.

Low-temperature photoluminescence spectra of layered semiconductor TlGaS2 Hasanlı, Nızamı; Bek, Alpan; Yılmaz, İsmail Ömer (Elsevier BV, 1998-1) Photoluminescence (PL) spectra of TlGa& layered single crystals were studied in the wavelength region 500-860 nm and in the temperature range 9.5-293 K. We observed a total of three PL bands centered at 568 nm (2.183 eV, A-band), 718 nm (1.727 eV, B-band) and 780 nm (1.590 eV, C-band) at various temperatures. We have also studied the variations of the A- and B-band intensities vs excitation laser density in the range from 7 X 10e2 to 9 W cm-‘. The A- and B-bands were found to be due to radiative transitions...
Low-temperature photoluminescence study of GaS0.5Se0.5 layered crystals Aydinli, A; Hasanlı, Nızamı; Goksen, K (2001-09-01) Photoluminescence (PL) spectra of GaS0.5Se0.5 layered single crystals have been studied in the wavelength range of 565-860 nm and in the temperature range of 15-170 K. Two PL bands centered at 585 nm (2.120 eV) and 640 nm (1.938 eV) were observed at T = 15 K. Variations of both bands were studied as a function of excitation laser intensity in the range from 10(-3) to 15.9 W cm(-2). These bands are attributed to recombination of charge carriers through donor-acceptor pairs located in the band gap. Radiative ...
Low-temperature photoluminescence in layered structured TlGa0.5In0.5Se2 crystals Hasanlı, Nızamı (2013-01-15) Photoluminescence (PL) spectra of TlGa0.5In0.5Se2 layered crystals have been studied in the wavelength region of 900-1020 nm and in the temperature range of 10-61 K. A broad PL band centered at 951 nm (1.304 eV) was observed at T = 10 K. Variations of emission band has been studied as a function of excitation laser intensity in the 0.15-51.5 mW cm(-2) range. The analysis of the spectra reveals that the peak energy position changes with laser excitation intensity (blue shift). This behavior of the emission b...
Low-temperature visible photoluminescence spectra of TlGaSe2 layered crystal Hasanlı, Nızamı; Aydinli, A; Baten, SMA (2000-02-01) 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 a slightly asymmetric Gaussian lineshape with a peak position located at 1.937 eV (640 nm) at 8.5 K. The PL is quenched with increasing temperature. The blue shift of the PL peak and the sublinear increase of the PL intensity with increasing laser intensity is explained using the inhomoge...
Low-temperature photoluminescence in CuIn5S8 single crystals Hasanlı, Nızamı (2016-06-01) Photoluminescence (PL) spectra of CuIn5S8 single crystals grown by Bridgman method have been studied in the wavelength region of 720-1020 nm and in the temperature range of 10-34 K. A broad PL band centred at 861 nm (1.44 eV) was observed at T = 10 K. Variations of emission band has been studied as a function of excitation laser intensity in the 0.5- 60.2 mW cm(-2) range. Radiative transitions from shallow donor level located at 17 meV below the bottom of the conduction band to the acceptor level located at...
