High-efficient microwave synthesis and characterisation of SrSnO3 / Imberger, Jörg in Chemical engineering journal, Vol. 155 N° 3 (Decembre 2009)  

Public ISBD [article]  inChemical engineering journal > Vol. 155 N° 3 (Decembre 2009) . - pp. 905-909 Titre : High-efficient microwave synthesis and characterisation of SrSnO3 Type de document : texte imprimé Auteurs : Imberger, Jörg, Auteur ; Rafael Libanori, Auteur ; Mario L. Moreira, Auteur Année de publication : 2010 Article en page(s) : pp. 905-909 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : SrSnO3 Microwave Nanostructures Photoluminescence Index. décimale : 660 Résumé : Strontium stannate (SrSnO3) nanostructures were obtained by microwave-assisted calcination of a SrSn(OH)6 precursor powder. Compared to other conventional calcination methods mentioned in the literature, this procedure led to a remarkable decrease of the reaction time and the synthesis temperature owing to direct interaction of radiation with the material. X-ray diffraction (XRD), field-emission scanning electron microscopy (FE-SEM) and photoluminescence measurements were performed. A comparison of the characterisation results obtained by microwave and conventional methods was conducted, and differences concerning the properties of conventionally high-temperature calcined SrSnO3 from that obtained by microwave-assisted calcination were observed. Furthermore, two different morphologies (nanosticks and nanobrushes) were obtained by a variation of the concentration of the reactants.
