The impact of childhood abuse on adult self-esteem and emotional regulation

Abstract

The evolution of photoluminescence (PL) spectra with increasing ?-irradiation dose was monitored for undoped and Cl-doped CdTe crystals. The emission intensities and the Huang-Rhys factors for different PL lines were determined as a function of the exposure dose. In irradiated CdTe:Cl, an irradiation-induced enhancement of the electron-phonon coupling for the A-center PL was attributed to decreasing concentration of the donor-acceptor pairs responsible for this band. Gamma-irradiation of undoped CdTe at a dose larger than 10kGy resulted in quenching of the A-center PL at 1.4eV, the donor-acceptor line in the edge luminescence at 1.55eV, as well as emission of the donor-bound excitons. Observed peculiarities are explained by a decrease of concentration of isolated donors, presumably through the creation of complexes with intrinsic defects generated by ?-rays. � 2003 Elsevier B.V.
