“…Moreover, the visible emission spectrum in the 400-700 nm range indicates several overlapped peaks, which can be barely distinguished and perhaps inferred in terms of luminescence centers. The peaks at 520 nm and 530 nm are also attributed to the presence of deep levels in Mn 2 O 5 [27].…”

HoMn2O5was synthesized by sol-gel auto combustion method and analyzed through x-ray diffraction, Fourier transform infrared reflectivity, Raman, UV-visible, Photoluminescence spectroscopies at room temperature and transport properties (applying dc- and ac- electric field) at high temperatures. Structural characterizations revealed single-phase nature and the analysis confirms the crystal structure by Rietveld refinement with orthorhombic symmetry (space group Pbnm). Both Scherer formula and Williamson-Hall analysis have been used to estimate the average grain size; the results come in good agreement. The reflectivity spectrum was fitted by the Lorentz oscillator model to account for the infrared active optical phonons. The Raman spectrum was measured in unpolarized geometry using a 514 nm laser excitation source, which confirmed its orthorhombic crystal structure. UV-visible spectroscopy demonstrated the electronic structure and semiconducting behavior of sample with an estimated bandgap of 1.54 eV. PL spectrum suggested its electronic transition and vibrations of Mn-O bonds. The conduction mechanism was investigated by measuring electrical resistivity in temperature range (293-473K) by two probe method. Dielectric properties have been discussed in terms of variation in dielectric constant, tangent loss, and conductivity as a function of temperature and frequency.

“…Moreover, films fabricated with Ba-Sn mixture are suitable candidates for use in flexible and transparent device applications with their favorable optoelectronic properties properties. [25][26][27][28][29][30] Herein, the supercapacitor behaviors of all electrodes produced were investigated using CV, GCD and EIS tests with a three electrode system. The 3 mg ml À1 Ba:Sncodoped electrode exhibited 7.7 times higher capacitance than undoped PEDOT:PSS electrode material and also potential range reach up to 2.0 V in 3.0 M KCl aqueous electrolyte.…”

In this work, high‐performance ZnO–SnO2 binary ceramic targets for magnetron sputtering of transparent conductive oxide (TCO) films were prepared by pressureless oxygen atmosphere sintering. The sintering behavior and densification mechanism of the ZnO–SnO2 binary targets were analyzed by systematically studying the oxide powder state, formation process of the solid reaction phase, and evolution of the target microstructure. The data revealed that the ZnO–SnO2 powder treatment improved the sintering activity and the powder dispersion; furthermore, it promoted a mutual reaction between the different components during sintering and the homogeneity of the target composition. The densification of the pure SnO2 ceramic target was difficult to achieve, and the addition of ZnO led to a continuous interaction between the ZnO and SnO2 components. The Zn2SnO4 phase started to form, and a temporary shrinkage of the target occurred above 800°C. After formation of the stable Zn2SnO4 and SnO2 phases, the target shrunk rapidly with increasing temperature, densification occurred during growth, and the two phases started to interact. The sintering temperature provided the driving force for the target densification, with the densification activation energy of the ZnO–SnO2 binary ceramic target estimated to be 580 kJ/mol based on the master sintering curve. A binary ceramic target with a high density (99.78% relative density), a fine grain size, and a homogeneous phase structure was achieved at a temperature of 1600°C. These findings are promising for the further improvement and performance enhancement of SnO2‐based materials.
