Efficient light scattering from one-pot solvothermally derived TiO2 nanospindles / Jun Jiang in Industrial & engineering chemistry research, Vol. 50 N° 15 (Août 2011) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 50 N° 15 (Août 2011) . - pp. 9003–9008 Titre : Efficient light scattering from one-pot solvothermally derived TiO2 nanospindles Type de document : texte imprimé Auteurs : Jun Jiang, Auteur ; Feng Gu, Auteur ; Xiang Ren, Auteur Année de publication : 2011 Article en page(s) : pp. 9003–9008 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Titanium  oxide  Light  scattering Résumé : one-pot solvothermal approach has been developed for the synthesis of single-crystal anatase TiO2 nanospindles. The introduction of adscititious water in nonaqueous reaction mixture is critical for the spindle formation by allowing for a slow growth rate of TiO2 to facilitate the shape control of TiO2 nanospindles. Arising from the prominent light scattering effect, the fabricated dye sensitized solar cells with the TiO2 nanospindles as light scattering layer show a 27% increment of energy conversion efficiency compared to that of P25 single layer film.

Morphological evolution from SnO2 quantum dots to quantum chains inside channels of mesoporous spheres / Feng Gu in Industrial & engineering chemistry research, Vol. 50 N° 22 (Novembre 2011) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 50 N° 22 (Novembre 2011) . - pp. 12542-12547 Titre : Morphological evolution from SnO2 quantum dots to quantum chains inside channels of mesoporous spheres Type de document : texte imprimé Auteurs : Feng Gu, Auteur ; Xiang Ren, Auteur ; Zhang, Jian, Auteur Année de publication : 2012 Article en page(s) : pp. 12542-12547 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Morphological  quantum  Mesoporous Résumé : Morphological evolution from SnO2 quantum dots (QDs) to quantum chains (QCs) confined in channels of mesoporous silica (MS) has been studied systematically in this work by varying the nuclei quantity deposited on the channels’ inner surface under hydrothermal conditions. Decreasing the MS amounts could influence the nuclei quantity and the subsequent crystal growth as well as the assembly process to form QCs by oriented attachment inside the channels. It is interesting to find that the evolution of SnO2 QDs→QCs systems would induce the variation of strain type tolerated, simultaneously, from tensile to compressive strain, and also exhibit morphology-dependent photoluminescence properties.
