Abstract

The crystal structure and the luminescent properties of TlZn(PO₃)₃ are studied with respect to Tl⁺ stereochemistry. In this polyphosphate the Tl⁺ ions are located in tunnels created by the zinc polyphosphate network [Zn(PO₃)₃]. Actually the thallium atoms are found in a disymmetric configuration and bond calculation allows the determination of the coordination number by oxygen: 6. Nevertheless a large Tl-O distance induces a low stereochemical activity of the 6s² lone pair. The luminescent properties are analyzed in the context of Fukuda's model. Thermal variations of excitation and emission spectra can be explained by the small influence of the electron-lattice interaction in agreement with the thallium environment. (C) 2000 Academic Press.
