Estudo teórico das propriedades ópticas dos BaWO4 e PbWO4
(Universidade Federal de São Carlos, 2012-09-21)
Among the scheelites, we highlight the Barium Tungstats (BaWO4) and lead tungstate (PbWO4). These compounds can be synthesized by various synthetic routes. However, we can highlight the hydrothermal synthesis method assisted ...
Estudo das propriedades fotoluminescentes do ZnS e ZnS:Eu obtidos pelo método solvotérmico assistido por microondas
(Universidade Federal de São Carlos, 2012-07-20)
This paper is about the synthesis, characterization and studies of nanostructures of ZnS and ZnS:Eu3+ prepared by microwave-assisted solvothermal method. The influence of the synthesis time in the microwave on the samples ...
Titanatos de alcalinos terrosos : a ordem associada à desordem
(Universidade Federal de São Carlos, 2010-02-26)
The microwave-assisted hydrothermal method was implemented in the synthesis of alkaline earth titanates under ABO3 stoichiometric known as perovskites, being efficient and innovative. For that, OH- groups played an important ...
Estudo das propriedades ópticas e estruturais de nanocristais de ZnS, obtidos pelo método solvotérmico aquecido por microondas
