Effect of calcium doping on LaCoO3 prepared by Pechini method

Powder Technology, 2013
Abstract Calcium doped lanthanum cobaltite (La1 − xCaxCoO3) (x = 0, 0.2, 0.4, 0.6, 0.8) with different concentrations has been prepared by modified Pechini type polymerizable method. The X-ray diffraction pattern of the calcium doped samples shows the formation of perovskite material in cubic structure.

Crystallization mechanism of LiNiO2 synthesized by Pechini method

Journal of Crystal Growth, 2001
Abstract Submicron and stoichiometric LiNiO 2 was successfully crystallized at low temperatures using Pechini method, which was developed to crystallize mixed cation oxide from organic precursors. The crystal structure and the effect of oxygen were investigated in this study.

Bismuth germanate films prepared by Pechini method

Optical Materials, 2010
Abstract Bismuth germanate films were prepared by dip coating and spin coating techniques and the dependence of the luminescent properties of the samples on the resin viscosity and deposition technique was investigated. The resin used for the preparation of the films was obtained via Pechini method, employing the precursors Bi2O3 and GeO2.

The blue phosphor Sr2CeO4 synthesized by Pechini’s method

Journal of Alloys and Compounds, 2001
Abstract Blue emitters are very attractive research subjects because of their possible industrial applications as phosphors for field emission displays. Recently, a blue phosphor, Sr 2 CeO 4 , was identified by a combinatorial materials synthesis technique.

Preparation of nanocrystalline ferroelectric BaBi4Ti4O15 by Pechini method

Materials Letters, 2006
A gel was formed when an aqueous solution of BaCl2, BiNO3, TiOCl2 and citric acid in stoichiometric ratio is heated on a water bath. This gel on decomposition at 600 °C produced the nano crystallites of ternary oxide, BaBi4Ti4O15 (BBT). The phase contents and lattice parameters were studied by the powder X-ray diffraction (XRD).

BaTi1–xZrxO3 nanopowders prepared by the modified Pechini method

Journal of Thermal Analysis and Calorimetry, 2007
The results reported here based on a study of BaTi1–xZrxO3 (x=0, 0.2 and 1) nanometric powders prepared by the modified Pechini method. The powder samples annealed from 600 to 1000°C/2 h were characterized by thermogravimetric analysis (TG), differential scanning calorimetry (DSC), X-ray diffraction (XRD) and scanning electron microscopy (SEM ...

Synthesis and dielectric properties of K1.6Fe1.6Ti6.4O16 ceramics produced by the Pechini method

Journal of Advanced Materials and Technologies, 2022
Potassium titanate modified with Fe3+ ions matching the stoichiometry of K1.6Fe1.6Ti6.4O16 (KFTO) was obtained by the polymer complex precursor method (Pechini method). The phase composition and morphology of the obtained sample were characterized using XRD, laser diffraction, and SEM technique.

Synthesis and luminescent properties of YGG:Tb phosphors by Pechini method

Journal of Luminescence, 2007
Abstract A novel green phosphor Y 3 Ga 5 O 12 :Tb (YGG) was successfully synthesized by Pechini method. The differential scanning calorimetric (TG-DSC) analysis and X-ray powder diffraction were used to determine the crystallization temperature and the pure phase phosphors were obtained by calcining the gel at 800 °C.

Synthesis and characterization of nanocrystalline Yb:Lu2O3 by modified Pechini method

Materials Science and Engineering: B, 2008
Abstract Cubic nanocrystalline Yb:Lu 2 O 3 in the size range of 50–100 nm were synthesized by modified Pechini sol–gel method. Differential thermal analysis and thermogravimetric analysis (DTA–TG) were used to study the thermal evolution of the precursor powder. Moreover, together with the results of X-ray powder diffraction (XRD) indicated that the
