Investigations of structural, optical, electrical and photocatalytic behavior of ZnO:N thin films for p-type substrate: Influence of annealing temperature

Co‐, Ni‐, and Cu‐Doped Fe‐Based Catalysts for the Microwave‐Assisted Catalytic Pyrolysis of Polyethylene

“…The XRD spectrum of the Fe 1 O x sample shows diffraction peaks at 18.27°, 30.09°, 35.42°, 37.05°, 43.05°, 53.39°, 56.64°, 62.51°, and 73.94°, with the peak at 35.42° corresponding to the (311) crystal plane of Fe 3 O 4 (PDF#19‐0629), [32] which was identified as the predominant structure in the sample. In addition to peaks related to Fe 3 O 4 , the spectrum of the Ni 1 Fe 1 O x sample exhibits peaks at 44.27°, 51.53°, and 75.86°, corresponding to the (111), (200), and (220) crystal planes, respectively, of a Ni/Fe alloy (PDF#38‐0419) [33] . The peak at 43.05°, associated with Fe 3 O 4 (400), is slightly more intense in the spectrum of Ni 1 Fe 1 O x than in that of Fe 1 O x , indicating an stronger interaction between Fe and Ni; this, in addition to an increase in the diffraction intensity, may result in interference between nearby peaks.…”

The role of annealing in optimizing the electrical, linear, and nonlinear optical properties ZIf-8@TiO2 films for possible use in photonic and optoelectronic devices

“…The nonlinear parameters were also evaluated using Miller's formula based on the linear parameters. By studying how annealing affects the structural, electrical, and optical properties of ZIF-8@TiO 2 films, one can assess the durability and longevity of the material in optical devices and sensors, as well as its stability under various environmental conditions [19][20][21][22]. The annealing process can enhance the durability of materials by relieving internal stresses, improving structural stability, and optimizing mechanical propertiesAdditionally, we can determine the material's suitability for applications that demand consistent and efficient electrical conductivity over time.…”

Aloe vera assisted green synthesis of Ag and Cu co-doped ZnO nanoparticles and a comprehensive analysis of their structural, morphological, optical, electrical and antibacterial properties

“…Among these, ZnO NPs are notable for having a large exciton binding energy, a direct energy band gap between 3.1 and 3.3 eV, and wide band gap semiconductor characteristics [ 6 ]. Their diverse applications into span optoelectronic devices [ 7 , 8 ], biosensors [ 9 ], disease diagnosis [ 10 , 11 ], antibacterial agents [ 12 , 13 ], solar cells [ 14 ], photocatalysis [ 15 ] and energy storage devices [ 16 ] are significant in the current scientific world. Zinc oxide nanoparticles have become highly sought-after in the fields of solar cell and energy storage technologies due to their distinctive properties, which include a wide bandgap, excellent electrical conductivity, and a high surface area.…”
