Enhanced luminescence of Tb3+/Eu3+ doped tellurium oxide glass containing silver nanostructures
(American Institute of Physics (AIP), 2009-05-15)
We report on energy transfer studies in terbium (Tb3+)-europium (Eu3+) doped TeO2-ZnO-Na2O-PbO glass containing silver nanostructures. The samples excitation was made using ultraviolet radiation at 355 nm. Luminescence ...

Evaluation of cytoprotective effects of compounds isolated fromCopaifera langsdorffiiDesf. against induced cytotoxicity by exposure to methylmercury and lead
(Taylor & Francis Ltd, 2020-09-01)
Copaifera langsdorffiiL. is one of the most known medicinal species in Brazil. Its leaves are rich in phenolic compounds with potential biological activities as an antioxidant and chelating agent. This paper reports the ...
The influence of the sintering system on PMN properties
(2003-03-15)
PMN powder samples with PbO excess of 0, 1,2 and 3% were submitted to the pressing and sintering at 1200°C for 4h with a heating rate of 3°C/min. A new sintering system, developed at our laboratories, was used. It allows ...

Nonlinear optical absorption of antimony and lead oxyhalide glasses
(2003-12-16)
The optical limiting behavior and nonlinear optical properties of antimony and lead oxyhalide glasses were discussed. The large nonlinear absorption coefficients which range from 11 to 20 cm/GW was determined using standard ...
