“…Zinc oxide (ZnO) is a II-VI semiconductor with wide direct band gap energy (3.37 eV) at room temperature, that is suitable for short wavelength optoelectronic applications and it has a large exciton binding energy (60 meV). Due to its properties like low cost, non-toxicity, abundance in nature, suitability to doping, ZnO has got wide device applications in different areas such as ultraviolet light-emitters, gas sensors, piezoelectric transducers, and solar cells [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15].…”

Zn1−xMnxO (x = 0.00, 0.01, and 0.05, respectively) was synthesized by using solid state reaction method. The structural properties were characterized by using X-ray diffraction and scanning electron microscopy. Optical properties were investigated by UV-visible spectroscopy. X-ray diffraction patterns indicate that all samples have hexagonal wurtzite structure without any impurity phases. The diffraction intensity increases and the peak position shifts to a lower 2θ angle with Mn concentration. The lattice parameters a and c, the volume of unit cell increase with Mn content indicating that Mn 2+ ions go to Zn 2+ ions in ZnO lattice. The grain size increases with Mn doping while the microstrain and dislocation density decrease. UV-vis spectra of the samples show that undoped ZnO sample has an energy band gap Eg of 3.34 eV. The optical study indicates a red shift in the absorbance spectra and a decrease in the band gap Eg with Mn content. This decrease of band gap may be attributed to the influence of dopant ions. The morphology and grain distribution of ZnO samples were analysed by scanning electron microscopy. The particle sizes are higher in doped samples when compared to the undoped sample and the surface roughness increases with Mn content. The grains are closely, densely packed and pores/voids between the grains increase with Mn content.

“…20 These distinguishing characteristics support this material's suitability for many fascinating applications such as photovoltaic, solar energy, luminescent, light-emitting, spintronic devices, UV light emitters, cancer therapies, antibacterial activity. [21][22][23][24][25][26][27][28] On the other hand, synthesis strategies have dominant impacts on the ZnO's physical properties. There are several methods to synthesize metal oxide nanostructures including coprecipitation, sol-gel method, hydrothermal, spray pyrolysis, sonochemical, chemical vapor deposition.…”

Detection of trace quantities of pharmaceutical drug ofloxacin (OFL) must be very simple and accurate. Innovative honeycomb-like structures have received considerable attention over the years due to their superior electrochemical and mechanical character. Herein, rod-shaped Bi2O3/ZnO and multiwalled carbon nanotubes were assembled to form a honeycomb structure like nanocomposite (hc-Bi2O3/ZnO:f-MWCNT). The new hc-BZM was synthesized via the cost-effective sonochemical method. A simple and convenient electrochemical determination of OFL was developed based on hc-BZM modified GCE. The physicochemical and electrochemical characterization was investigated by CV and DPV. The respective calibration curve has good linearity with current vs the concentration of OFL in the range of 0.5 to 39 μM with a correlation coefficient of R2 = 0.991. From the calibration curve slope, the detection limit and sensitivity were determined to be 0.03 μM and 1.063 μA μM–1 cm–2. The proposed sensor explained the structural advantages of simple design, low cost, wide linear range, good selectivity, and reusability. Also, the suggested hc-BZM composites can provide a new platform for the simultaneous determination of OFL, PXM, and DA. Finally, the sensor was successfully applied for the determination of OFL in human urine and serum sample, the obtained results have good agreement with added and the recovery value.
