Abstract
Ti K-edge XANES spectra of KTiOPO4, an important material for second harmonic generation (SHG) and several of its isomorphs including MTiOPO4 (M = Na, Ag) and KTi1-xSnxOPO4 (x = 0.1, 0.4, 0.5, 0.6) have been recorded. The pre-edge regions of these spectra exhibit characteristic features that are assigned to electronic transitions from the Ti 1s to the unoccupied Ti 3d and 4p levels. The intensities of these pre-edge features are very sensitive to slight changes in the asymmetry of the octahedral Ti coordination sphere. Thus, in the series KTi1-xSnxOPO4 the successive substitution of Ti by Sn causes a substantial decrease of the Ti coordination asymmetry. This decrease is correlated with a loss in SHG intensity.
