摘要：
TlGaS2, TlGa0.99Fe0.01S2 and TlGa0.98Fe0.02S2 single crystals were grown by the modified Bridgman Stockbarger method. They did not have cracks and voids on their surface. The absorption measurements were carried out on TlGaS2, TlGa0.99Fe0.01S2 and TlGa0.98Fe0.02S2 samples in the temperature range 10-320 K with steps of 10K. The phonon energies calculated for TlGaS2, TlGa0.99Fe0.01S2 and TlGa0.98Fe0.02S2 are (19.70 +/- 5), (40.2 +/- 5) and (15.1 +/- 5) meV, respectively. The first and second defect levels have been found as 2.423 and 2.569 eV for TlGa0.99Fe0.01S2 and as 2.017 and 2.426 eV for TlGa0.98Fe0.02S2 at 10 K, respectively.
