摘要：

Vibrational spectroscopy data were used to gain insight into the possible locations of extra oxygen ions introduced into La8+xSr2-y(SiO4)(6)O2+delta compounds to raise their ionic conductivity. Perturbations observed in the Raman and infrared spectra of these compounds with increasing delta were explained by using the at, initio calculation results for the fully stoichiometric (x = y = delta = 0) lattice. This allowed the inference that the extra oxygen ions are incorporated into La-O tunnel-like fragments inherent in the studied structures. Copyright (C) 2010 John Wiley & Sons, Ltd.
