Quantum-sized ZnO nanoparticles: Synthesis, characterization and sensing properties for NO2

Influence of processing methodology on the structural and magnetic behavior of MgFe2O4 nanopowders

“…The peak broadening of the diffraction pattern is mainly due to four factors: microstrains (deformation of the lattice), faulting (extended defects), crystalline domain size and domain size distribution [12]. If we assume that the samples are free of strains and faulting, the peak broadening is only due to the crystalline domain size [13]. According to the Debye-Scherrer formula, the average crystallite size can be estimated from the half-width of the most intense peak (3 1 1).…”

Quantum-sized ZnO nanoparticles synthesized in aqueous medium for toxic gases detection

“…Thus, various synthesis methods of quantum-sized ZnO have been reported, such as vapor condensation, thermal evaporation, spray pyrolysis, magnetron sputtering, metal organic chemical vapor deposition, and sol-gel, etc. [5][6][7][8][9]. Among them, the sol-gel route has attracted much attention due to their low treatment temperature, low cost and high efficiency.…”

Two-Dimensional Zinc Oxide Nanostructures for Gas Sensor Applications

“…Therefore, many efforts have been devoted to the synthesis of ZnO nanostructures including quantum nanoparticles [20] nanorods [21], nanofibers [22], nanotubes [23], and three-dimensional (3D), hierarchical nanostructures [24]. However, most of them aimed at an investigation of the effects of morphology and crystal size on the sensing behavior but not on the exploration of their crystal plane-dependent properties.…”
