“…For the air annealed sample, the peak occurred at 395.93 eV, suggesting the presence of significant amounts of N in the form of surface species of N–C and N–N. [ 2 ] For vacuum annealed samples, the peak at 400.27 eV suggests the presence of nitrogen‐doped at the oxygen sites and hence the formation of Zn–N bonding in the crystal lattice, [ 38 ] O–Zn–N and Zn–N linkage and may also be attributed to the presence of N 3− ions in oxynitrides. [ 39 ] From the fitting spectra, the amounts of different types of chemical structures present in the samples are listed in Table 5 , and the percentage compositions of all the elements are in Table 5.…”

Herein, the effect of the postannealing process on the structural properties of nitrogen‐doped Zinc oxide nanostructures (N‐ZnO) synthesized by a single‐step hydrothermal method is reported. Detailed structural and compositional characterizations are performed using X‐ray diffraction (XRD), X‐ray photoelectron spectroscopy (XPS), field emission scanning electron microscopy (FESEM), and energy‐dispersive spectroscopy (EDS). Also, the amount of nitrogen doping has been optimized using different concentrations of the precursor solutions and they are subjected to different postannealing environments. The postannealing process is found to alter the defect structure in ZnO significantly. The samples showing the highest nitrogen doping are further evaluated in detail to know their structural variations. The incorporation of nitrogen into the ZnO structure and the effects of the postannealing process substantially alter the electrochemical characteristics by changing the surface properties of ZnO nanosheets. The effect of these structural variations on the electrochemical performance of ZnO is also explored. Under optimized conditions, the highest conductivity of N‐ZnO nanostructures obtained suggests the material as an outstanding candidate for electrochemical applications.

“…It can be defined as the lattice constant distribution, such as lattice imperfections that occur from the crystal defects. 36 XRD data depict a shift in the peak position and variation in FWHM in all the samples deposited with different urea concentrations as correlated with the pure zinc oxide sample. This shift represents a strain produced on the host lattice during the deposition.…”

Pure and urea-modified zinc oxide thin films are prepared using the spray pyrolysis technique on microscopic glass substrates. We have added different urea concentrations as a modifier to the zinc acetate precursor for obtaining urea-modified ZnO thin films and investigated the effect of the urea concentration on the structural, morphological, optical, and gas-sensing properties. The gas-sensing characterization of pure and urea-modified ZnO thin films is tested in the static liquid distribution technique with 25 ppm of ammonia gas at an operating temperature of 27 °C. The prepared film with a concentration of 2 wt % of urea has shown the best sensing properties toward ammonia vapors due to more active sites for the reaction between chemiabsorbed oxygen and the target vapors.
