Abstract:

Electronic structure properties of undoped single crystals of KPb2Cl5 (KPC) and RbPb2Cl5 (RPC) have been studied using low-temperature (T = 8 degrees K) far ultraviolet (3.7-24 eV) synchrotron radiation spectroscopy. Dispersions of optical functions have been calculated. The electronic transitions at 4.4-5.0 eV were ascribed to the excitation of cationic excitons. The energy region of 5-9 eV was associated with the transitions from the valence band to the conduction band: 6(1)S(0) --> 6(1)P(1) at 6.28 eV, 6(1)S(0) --> 6(3)P(2) at 5.94 eV. The complex band at 7.87 eV was attributed to the excitation of anionic excitons. The 19-24 eV peaks were associated with the 5d --> 6p transitions in Pb2+ ions. (C) 2014 Optical Society of America
