Description
Antimony-doped K1-xTi1-xSbxOPO4, x=0.23, crystals have been prepared by spontaneous nucleation from the flux in the quaternary system K2O-TiO2-P2O5-Sb2O5. Crystal structure observation with TEM method reveals the presence of superstructure ordering. Core level electronic parameters have been studied by X-ray photoelectron spectroscopy. Strong effect of Sb doping has been detected for inner shells of Ti4+ ions. Prominent decreasing of the binding energy difference Δ(O 1s-Ti 2p3/2) correlates with the shortening of mean oxide bond length L(Ti-O) at x=0.23 that suggests increased ionicity of Ti-O bonds in K1-xTi1-xSbxOPO4 solid solutions
