Discovery of novel multifunctional photoluminescence materials are of great concern to the development of disciplinary crossing and integration. In this study, BaTiO3@ZnO multifunctional heterostructures and BaTiO3@ZnO:Eu ...
Photo-induced electrical behavior under gas adsorption on SnO2 -based heterostructures
(2020-11-15)
Er-doped SnO2 thin films are produced by a combined technique where films are deposited by resistive evaporation from a precursor powder obtained by sol-gel. Films are deposited on different substrates and analyzed concerning ...
Structural and optical properties of ZnS/MgNb2O6 heterostructures
(Elsevier B.V., 2015-03-01)
In this letter, we report a simple and efficient synthetic procedure where the first step is a coprecipitation/calcination method used to obtain magnesium niobate MgNb2O6 (MN) nanoctystals and in the second stage a microwave ...
Ozone sensing properties of nickel phthalocyanine:ZnO nanorod heterostructures
(2017-01-05)
We report on the chemiresistive gas sensing characteristics of ZnO nanorods (NRs) modified by a thin layer of nickel phthalocyanine (NiPc). Ozone detection was carried out through electrical measurements with an optimized ...
