Dielectric Behavior of alpha-Ag2WO4 and its Huge Dielectric Loss Tangent
(Univ Fed Sao Carlos, Dept Engenharia Materials, 2019-01-01)
The microwave-assisted hydrothermal method was used to obtain alpha-Ag2WO4. Rietveld refinement confirmed that alpha-Ag2WO4 is stable in the orthorhombic phase, without secondary phase. However, field-effect scanning ...
Blue and red light photoluminescence emission at room temperature from CaTiO3 decorated with α-Ag2WO4
(2017-05-01)
CaTiO3 (CT) and α-Ag2WO4 (AW) semiconductors are widely known for their interesting electrical and photoluminescence (PL) properties. In this study, we decorated CT with AW for obtaining CaTiO3:α-Ag2WO4 (CT:AW), and ...
