Photoluminescence of bulks and thin films of Eu3+-doped organic/inorganic hybrids
(Elsevier B.V. Sa, 2008-02-28)
Organic-inorganic hybrids formed by polyether-based chains grafted to both ends to a siliceous backbone through urea cross-linkages (-NHC=O)NH-), named di-ureasil, have been used as host for incorporation of Eu3+ in the ...
Problems related to the employment of thin uranium films as neutron dosimeters
(1995-12-01)
Thin uranium films built on muscovite mica basis and obsidian samples having known ages were irradiated with thermal neutrons at the IPEN/CNEN reactor, São Paulo. Comparing thin film performance with the obsidian one, it ...

Role of residual stress on phase transformations of Pb(Zr0.50Ti0.50)O3 thin films obtained from chemical route
(2016-07-14)
abstract: The effects of heat treatment on the phase transformations of lead zirconate titanate Pb(Zr0.50Ti0.50)O3 (PZT) thin films were studied. The pyrolysis temperature directly affected the densification, residual ...
Structural, dielectric, ferroelectric and optical properties of PBCT, PBST and PCST complex thin films on LaNiO3 metallic conductive oxide layer coated Si substrates by the CSD technique
(Elsevier B.V., 2014-10-05)
Ferroelectric thin films and LaNiO3 (LNO) metallic conductive oxide thin films were prepared by a chemical solution deposition (CSD) method. PBCT60, PBST60 and PCST60 ferroelectric thin films were grown on different ...
Influence of Mg on the structural and optical properties of LiNbO3 thin films grown by polymeric precursor method
(Trans Tech Publications Ltd, 2005-01-01)
A polymeric precursor solution was used to deposit pure and Mg doped LiNbO3 thin films on sapphire substrates by spin-coating. The effects of magnesium addition on crystallinity, morphology and optical properties of the ...
Influence of temperature on the microstructure and electrical properties of BBT thin films
(Taylor & Francis Ltd, 2003-01-01)
The BBT films were prepared by a spin-coating process from the polymeric precursor method (Pechini process). In order to study the influence of the temperature on the BBT microstructure and electrical properties, the films ...
The self-polarization effect in Pb(Zr0.50Ti0.50)O-3 thin films with no preferential orientation
(Pergamon-Elsevier B.V. Ltd, 2012-11-01)
This work demonstrates the existence of a self-polarization effect in Pb(Zr0.50Ti0.50)O-3 thin films with no preferential orientation. Piezoresponse Force Microscopy (PFM) and dielectric measurements were used to study the ...
Effect of annealing atmosphere on phase formation and electrical characteristics of bismuth ferrite thin films
(Pergamon-Elsevier B.V. Ltd, 2009-08-05)
Bismuth ferrite thin films were deposited on Pt/Ti/SiO(2)/Si substrates by a soft chemical method and spin-coating technique. The effect of annealing atmosphere (air, N(2) and O(2)) on the structure and electrical properties ...
