First principles calculations on the origin of violet-blue and green light photoluminescence emission in SrZrO3 and SrTiO3 perovskites
(Theoretical Chemistry Accounts, 2009-11-01) [Artigo]
The photoluminescence (PL) emission from SrZrO3 (SZ) and SrTiO3 (ST) crystalline, quasi-crystalline, and quasi-amorphous samples, prepared by the polymeric precursor method, was examined by ab initio quantum mechanical ...
Room temperature photoluminescence of BCT prepared by Complex Polymerization Method
(Current Applied Physics, 2010-01-01) [Artigo]
It was used the Complex Polymerization Method to synthesize barium calcium titanate powders (BCT). Crystalline Ba(0.8)Ca(0.2)TiO(3) perovskite-type phase could be identified by X-ray diffraction and confirmed by Raman ...
Structural Refinement and Photoluminescence Properties of MnWO4 Nanorods Obtained by Microwave-Hydrothermal Synthesis
(Journal of Inorganic and Organometallic Polymers and Materials, 2012-01-01) [Artigo]
Manganese tungstate (MnWO4) nanorods were prepared at room temperature by the co-precipitation method and synthesized after processing in a microwave-hydrothermal (MH) system at 140 degrees C for 6-96 min. These nanorods ...
beta-ZnMoO4 microcrystals synthesized by the surfactant-assisted hydrothermal method: Growth process and photoluminescence properties
(Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2012-02-20) [Artigo]
In this communication, we investigate the effect of different surfactants: cetyltrimethylammonium bromide (CTAB), sodium dodecyl sulfate (SDS) and polyvinylpyrrolidone (PVP-K40) on the growth process of zinc molybdate ...

(Polyhedron, 2013-04-30) [Artigo]
In this paper, a combined theoretical and experimental study on the electronic structure and photoluminescence (PL) properties of beta zinc molybdate (β-ZnMoO4) microcrystals synthesized by the hydrothermal method has been ...
Intense photoluminescence emission at room temperature in calcium copper titanate powders
(Ceramics International, 2013-05-01) [Artigo]
A study was undertaken about the structural and photoluminescent properties at room temperature of CaCu3Ti4O12 (CCTO) powders synthesized by a soft chemical method and heat treated between 300 and 800 °C. The decomposition ...
Effect of different surfactants on the shape, growth and photoluminescence behavior of MnWO4 crystals synthesized by the microwave-hydrothermal method
(Advanced Powder Technology, 2012-01-01) [Artigo]
In this communication, we report the effect of different surfactants [cetyltrimethylammonium bromide (CTAB), sodium dodecyl sulfate (SDS) and sodium bis(2-ethylhexyl)sulfosuccinate (AOT)] on the shape, growth and ...
CaTiO3 and Ca1-3xSmxTiO3: Photoluminescence and morphology as a result of Hydrothermal Microwave Methodology
(Ceramics International, 2016-01-01) [Artigo]
Calcium titanate (CaTiO3 - CT) and samarium doped calcium titanate (CaTiO3:Sm3+ - CT:Sm) powders in different Sm3+ concentrations (0.5-5.0% molar ratio of Sm3+) were obtained by the Hydrothermal Microwave Methodology at ...
Structural and optical properties of CaTiO3 perovskite-based materials obtained by microwave-assisted hydrothermal synthesis: An experimental and theoretical insight
(Acta Materialia, 2009-10-01) [Artigo]
CaTiO3 powders were synthesized using both a polymeric precursor method (CTref) and a microwave-assisted hydrothermal (CTHTMW) method in order to compare the chemical and physical properties of the perovskite-based material ...
