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 ...

Contribution of structural order-disorder to the green photoluminescence of PbWO4
(American Physical Soc, 2007-04-01)
An intense and broad visible photoluminescence (PL) band was observed at room temperature in structurally disordered PbWO4 thin films. The scheelite lead tungstate (PbWO4) films prepared by the polymeric precursor method ...

Estudo teórico das propriedades ópticas dos BaWO4 e PbWO4
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Química - PPGQ, 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 ...
Near-infrared Kerr nonlinearity of Pb(PO3)(2)-WO3 glasses
(American Institute of Physics (AIP), 2010-11-15)
We report measurements of the nonlinear refractive index, n(2), and the nonlinear absorption coefficient, alpha(2), of Pb(PO3)(2)-WO3 glasses. The measurements were performed using 100 fs (17 ps) laser pulses at 800 nm ...
