EXAFS and Raman spectroscopy study of binary indium fluoride glasses
Extended X-ray absorption fine spectroscopy (EXAFS) and Raman scattering studies of InF3-BaF2 and InF3-SrF2 binary glasses are reported. For all compositions, the local structure of the glasses is built with InF6 units. ...
Stabilization of fluoroindate glasses by magnesium fluoride
This paper describes the stabilizing effect of MgF2 on the binary system InF3-BaF2. A complete investigation of the In-Ba-Mg system led to samples up to 5 mm in thickness. Further optimization of this system was achieved ...
Mild bottom-up synthesis of indium(0) nanoparticles: Characterization and application in the allylation of carbonyl compounds
(Royal Society of Chemistry, 2016-02-26)
Very reactive, monodisperse (4.0 ± 0.5 nm) spherical indium(0) nanoparticles have been generated in situ, in a simple, mild and efficient way, by fast reduction of commercially available indium(iii) chloride with lithium ...
In(PO3)3 stabilised fluoroindate glasses
Results on thermal and optical characterization of new lanthanide containing fluoroindate glasses in the system InF3-BaF2-In(PO3)3 are presented. Good optical quality and very stable glasses presenting up to 5 mm in thickness ...
Study of the influence of indium segregation on the optical properties of InGaAs/GaAs quantum wells via split-operator method
(A V S AMER INST PHYSICS, 2010)
In the case of quantum wells, the indium segregation leads to complex potential profiles that are hardly considered in the majority of the theoretical models. The authors demonstrated that the split-operator method is ...
Synthesis of In2O3 nanoparticles by thermal decomposition of a citrate gel precursor
Assinalação Estereoquímica de Produtos e Descrição de Mecanismos para Reações de Acoplamento entre α,α- Diclorocetonas e Compostos Carbonílicos Promovidas por Brometo de Índio(I)
(Universidade Federal de Santa MariaBRQuímicaUFSMPrograma de Pós-Graduação em Química, 2007-02-28)
This work describes our results on the use of indium(I) bromide in Organic Synthesis, namely the reaction mechanisms and stereochemical outcome. Indium enolates, generated from the reaction between indium(I) bromide and ...
Chlorine evolution during the fusion of chlorofluoroindate glasses
Samples with a composition of 40InF 3-20ZnF 2-5MCl- xBaF 2-ySrF 2, where M=Na, Li and x+y=35 mol%, were prepared. The thermal properties related to the Ba/Sr ratio and to the remaining chlorine content in the glasses were ...
