Effect of polyvinyl alcohol on the shape, photoluminescence and photocatalytic properties of PbMoO4 microcrystals
Araújo, Vinícius Dantas; Tranquilin, R. L.; Motta, F. V.; Paskocimas, C. A.; Bernardi, Maria Inês B.; Cavalcante, Laécio Santos; Andres, Juan; Longo, Elson; Bomio, M. R. D. Elsevier (2014)For this study, lead molybdate (PbMoO4) microcrystals were prepared by the co-precipitation method and processed using a conventional hydrothermal method at 100 °C for 10 min with polyvinyl alcohol (PVA) as the capping ... -
Experimental and theoretical study to explain the morphology of CaMoO4 crystals
Oliveira, F.K.F.; Carvalho de Oliveira, Marisa; Gracia, Lourdes; Tranquilin, R. L.; Paskocimas, C. A.; Motta, F. V.; Longo, Elson; Andres, Juan; Bomio, M. R. D. Elsevier (2018-03)CaMoO4 crystals were prepared by a controlled co-precipitation method and processed in a domestic microwave-assisted hydrothermal system with two different surfactants (ethyl 4-dimethylaminobenzoate and 1,2,4,5-benzenete ... -
