Abstract

The measurements of spectral and temperature dependences of photoconductivity and photo-electromotive force of Tm_2S_3 thin films doped with Pb and Cd in the region of photon energy of 0.3 – 3.3 eV and at the temperatures of 110 – 350 K have been carried out. Obtained experimental results have been interpreted with supposition of basic role of photosensitivity of acceptor levels formed by vacancies in cations’ sublattice during their compensation by the introducing of Pb and Cd donors. The ionization energies of Pb-donor and Tm-vacancy acceptor levels in Tm_2S_3 films have been determined.
