Preparation, structural and optical characterization of BaWO4 and PbWO4 thin films prepared by a chemical route
(Elsevier B.V., 2003-01-01)
Polycrystalline BaWO4 and PbWO4 thin films having a tetragonal scheelite structure were prepared at different temperatures. Soluble precursors such as barium carbonate, lead acetate trihydrate and tungstic acid, as starting ...

Structural study of tungstate fluorophosphate glasses by Raman and X-ray absorption spectroscopy
(Elsevier B.V., 2005-05-01)
Transparent glasses were synthesized in the NaPO3-BaF2 WO3 tertiary system and several structural characterizations were performed by X-ray absorption spectroscopy (XANES) at the tungsten L-I and L-III absorption edges and ...
Synthesis, Characterization, Anisotropic Growth and Photoluminescence of BaWO4
(Amer Chemical Soc, 2009-02-01)
This paper reports on the synthesis of barium tungstate (BaWO4) powders obtained by the coprecipitation method and processed in a domestic microwave-hydrothermal (MH) at 413 K for different times. These powders were analyzed ...
Synthesis, growth process and photoluminescence properties of SrWO4 powders
(Academic Press Inc. Elsevier B.V., 2009-02-01)
SrWO4 powders were synthesized by the co-precipitation method and processed in a microwave-hydrothermal (MH) at 140 degrees C for different times. The obtained powders were analyzed by X-ray diffraction (XRD), micro-Raman ...
Efeito de compensação de cargas nas propriedades luminescentes dos materiais 'BA''WO IND.4':'EU POT.3+','LI POT.+'
(Universidade Estadual Paulista (UNESP), 2014)
Photoluminescent property of mechanically milled BaWO4 powder
(Elsevier B.V., 2007-10-01)
Crystalline BaWO4 (BWO) powder obtained by the polymeric precursor method was structurally disordered by means of high-energy mechanical milling. For the first time a strong and broad photoluminescence (PL) has been measured ...
Crystallization of monoclinic WO3 in tungstate fluorophosphate glasses
(Elsevier B.V., 2009-03-15)
Tungstate fluorophosphate glass compositions with high WO3 concentration were prepared in the ternary system (80-0.8x)NaPO3-(20-0.2x)BaF2-xWO(3) with x = 40,50 and 60 mol%. Transparency decreases as WO3 concentration ...
