Solid State NMR studies of functional oxidesFerrara, Chiara 06 February 2014 (has links) (PDF)
The functional oxides are performing materials showing interestant properties. The study of the local environment respect to the average struvture is essential for the deep understanding of the correlations between structure and properties ; this investigation of short and medium range can be performed with the use of solid state NMR techniques. In particular in this thesis three different classes of materials for applications in fields of optic and energy are considered : perovskite structure LaSrAlO4, the melilite system LaSr(Ga/Al)3O7 and the family of orthosylicates Li2(Fe/Mn)SiO4.

Solid State NMR studies of functional oxides / Etudes d'oxides fonctionnelles par RMN à l'état solideFerrara, Chiara 06 February 2014 (has links)
Les oxydes fonctionnels sont des matériaux qui manifestent des propriétés intéressantes. L'étude de l'environnement local par rapport à la structure moyenne idéale est essentiel et peut être fourni par l'utilisation de techniques modernes de résonance magnétique nucléaire (RMN). Le travail présenté dans cette thèse suit et développe ces approches combinées pour l'enquête de trois classes différentes d'oxydes fonctionnels qui trouvent des applications dans des domaines d'intérêt technologique pertinente, comme l'optique et de l'énergétique : système perovskite LaSrAlO4, mélilite LaSr(Ga/Al)3O7 et la famille de orthosilicates Li2(Fe/Mn)SiO4. / The functional oxides are performing materials showing interestant properties.
