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.

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.</abstract><note type="content">Section title: Regular Article</note><subject lang="en"><genre>Keywords</genre><topic>TlZn polyphosphate structure</topic><topic>Tl+ stereoactivity</topic><topic>Tl+ luminescence</topic><topic>lone pair effect.</topic></subject><relatedItem type="host"><titleInfo><title>Journal of Solid State Chemistry</title></titleInfo><titleInfo type="abbreviated"><title>YJSSC</title></titleInfo><genre type="journal">journal</genre><originInfo><dateIssued encoding="w3cdtf">20001101</dateIssued></originInfo><identifier type="ISSN">0022-4596</identifier><identifier type="PII">S0022-4596(00)X0018-7</identifier><part><date>20001101</date><detail type="volume"><number>154</number><caption>vol.</caption></detail><detail type="issue"><number>2</number><caption>no.</caption></detail><extent unit="issue pages"><start>321</start><end>644</end></extent><extent unit="pages"><start>584</start><end>590</end></extent></part></relatedItem><identifier type="istex">4EBF50C7241036975C91D6909702D32870B0483D</identifier><identifier type="DOI">10.1006/jssc.2000.8898</identifier><identifier type="PII">S0022-4596(00)98898-4</identifier><accessCondition type="use and reproduction" contentType="copyright">©2000 Academic Press</accessCondition><recordInfo><recordContentSource>ELSEVIER</recordContentSource><recordOrigin>Academic Press, ©2000</recordOrigin></recordInfo></mods></metadata><serie></serie></istex></record>Pour manipuler ce document sous Unix (Dilib)
