Synthesis of pure and La-doped anatase nanopowders by sol-gel and hydrothermal methods and their efficiency in photocatalytic degradation of alprazolam
(Ceramics International, 2014)
Pure and La3+ doped titanium dioxide (TiO2) nanopowders were obtained by sol gel and hydrothermal methods. A precursor was titanium tetrachloride and concentrations of dopants were 0.5 and 1.0 mol%. Procedures of both ...
Nanostructured Fe2O3/TiO2 thick films: Analysis of structural and electronic properties
(Ceramics International, 2015)
Thick films using starting nanopowders of TiO2 (anatase 99.7%) and alpha-Fe2O3 (hematite) mixed in the weight ratios 60:40 and 40:60 for thick film paste were fabricated by screen printing technology on an alumina substrate. ...
Ex-situ sensitization of ordered TiO2 nanotubes with CdS quantum dots
(Ceramics International, 2015)
Ordered titania nanotubes (pore diameter approximate to 90 nm and wall thickness approximate to 10 nm) were obtained by the anodization technique and used for the ex-situ deposition of cadmium sulfide quantum dots (CdS ...
Photoluminescence of europium(III)-doped (YxSc1-x)(2)O-3 nanoparticles: Linear relationship between structural and emission properties
(Elsevier, 2016)
Europium (III)-doped (YxSc1-x)(2)O-3 nanocrystalline powders of different compositions (x=0, 0.25, 0.5, 0.75 and 1) are synthesized using a polymer complex solution method. Comparative structural and optical characterization ...
Preparation of Y2O3:Eu3+ nanopowders via polymer complex solution method and luminescence properties of the sintered ceramics
(Ceramics International, 2011)
Herein we presented polymer complex solution method for production of well crystalline europium doped Y2O3 nanopowders. Polyethylene glycol (PEG) of five different molecular weights is used both as a fuel and as a nucleation ...
Structural, optical and photodegradation properties of pure and Fe-doped titania nanoparticles probed using simulated Solar light
(Elsevier, 2016)
We report the successful, low temperature synthesis of pure and Fe-doped titania nanoparticle (NP) powders, using organic Ti- and Fe-precursors. The properties of the synthesized titania based materials were obtained using ...
Fabrication of polycrystalline (Y0.7Gd0.3)(2)O-3:Eu3+ ceramics: The influence of initial pressure and sintering temperature on its morphology and photoluminescence activity
(Ceramics International, 2012)
Nanocrystalline (Y0.7Gd0.3)(2)O-3 powder, synthetised via polymer complex solution method, was compacted into 25 pellets applying high pressures (173-867 MPa) for 30 s that were subsequently sintered at different temperatures ...
Polycrystalline (Y0.7Gd0.3)(2)O-3:Eu3+ ceramics fabricated by Spark Plasma Sintering: Densification and microstructure development
(Ceramics International, 2014)
Using Spark Plasma Sintering it is possible to produce polycrystalline ceramics of very fine microstructure and good mechanical properties. This work presents the fabrication of such ceramics using Eu3+-doped (Y0.7Gd0.3)(2)O-3 ...
