Study of KCl + x% in and KCl + y% TlCl thin films
(1998-12-01)
The present work reports the study of KCl thin films doped with In+ or Tl+. Both systems show optical absorption bands similar to single crystals. As the impurity concentration increases, so does the absorption as also the ...

Síntese e caracterização estrutural de polialetos e compostos zwitteriônicos derivados de diteluretos de diarila
(Universidade Federal de Santa MariaBRQuímicaUFSMPrograma de Pós-Graduação em Química, 2016-06-22)
The present work describes the synthesis and structural elucidation of ten new tellurium halide starting from diaryl ditellurides (aryl group = 2-piridine or N,N-dimethylbenzilamine). The compounds and starting material ...
Síntese, caracterização e estudo da química de coordenação de novos compostos contendo Índio e Telúrio
(Universidade Federal de Santa MariaBRQuímicaUFSMPrograma de Pós-Graduação em Química, 2011-07-29)
In this work we describe the synthesis and characterization of the first indium
and tellurium compounds in which tellurium shows metallic behavior towards indium.
We have studied the coordination chemistry of indium and ...
Síntese e caracterização estrutural de novos haletos de telúrio e organiltelúrio(IV) com bromo e cloro
(Universidade Federal de Santa MariaBRQuímicaUFSMPrograma de Pós-Graduação em Química, 2013-09-18)
This work describes the synthesis and characterization of new tellurium and organiltellurium
(IV) halides, whereas the halogens chlorine and bromine were used. Despite being less stable
than the analogous iodine, these ...
Síntese, reatividade e caracterização estrutural de haletos de telúrio e ariltelurenila com estados de oxidação incomuns ou mistos.
(Universidade Federal de Santa MariaBRQuímicaUFSMPrograma de Pós-Graduação em Química, 2011-03-24)
This work presents a study related to the halogenation of diarylditellurides (RTe)2
in order to obtain tellurium and aryltellurenyl halides with unusual or mixed oxidation
states. Although regarded as essentially unstable, ...
