To study the effect of La<sup>3+</sup> doping on structural and electrical properties, a few compositions system Sr<sub>2−x</sub>La<sub>x</sub>NiMoO<sub>6−δ</sub> (<italic>x</italic> = 0.02, 0.04, 0.06, 0.08, 0.10) were synthesized <italic>via</italic> citrate–nitrate route.
Lanthanum (La3+)-doped double perovskites Sr2CoMoO6 (Sr2-xLaxCoMoO6, 0.00 ≤ x 0.03) were synthesized via the citrate-nitrate autocombustion route. The Reitveld refinement analysis of X-ray diffraction reveals tetragonal symmetry as main phase with space group I4/m and also confirms presence some peaks corresponding to extra SrMoO4. SEM micrograph images reflect that grains are in irregular shape sizes for all samples. Average grain size gradually decreases increase SrMoO4 phase....
Abstract The SrCe1-xLaxO3 (x = 0.0, 0.02, 0.4, 0.6, and 0.10) perovskite materials have been successfully synthesized by auto combustion method calcined at 1100°C. XRD patterns reveal a highly crystalline orthorhombic crystal structure with Pnma space group in all samples. TEM micrograph shows spherical morphology of 10 mol% La3+ doped SrCeO3 sample, the SAED pattern confirming its nature. incorporation ion has confirmed Raman Fourier transform infrared (FTIR) measurements. UV-vis absorption...
Lead‐free piezoelectric potassium niobate ( KNbO 3 ) system was synthesized by conventional solid‐state ceramic route. Rietveld analysis of X‐ray diffraction data this revealed that the sample crystallized in pure orthorhombic perovskite phase at room temperature. SEM micrograph depicted presence grains having diffuse brick structure with an average grain size 500 nm. Dielectric properties were investigated under different DC bias voltage a broad frequency (from 20 Hz to 1 MHz) and...
Lanthanum chromite (LaCrO3) was synthesized by two routes employing auto combustion and conventional solid state routes. Phase investigation of the prepared samples carried out powder X-ray diffraction techniques, which confirmed single phase formation. Rietveld analysis lanthanum exhibited orthorhombic structure with space group Pnma at room temperature. Well crystalline obtained calcination 1200°C technique 1000°C method. SEM images microstructure crystals nature agglomeration among them...
In the past two decades, organic conductors have been widely explored for use in different applications. One of extensively studied material field electronic devices is PEDOT:PSS. Organic/inorganic nanocomposite systems developed to improve properties materials. present study, we made an attempt understand effect low energy oxygen ion beam irradiation on electrical and structural PEDOT:PSS PEDOT:PSS/TiO2 nanocomposites. The observed reduction may be linked radiation induced phase change....
