“…Moreover, the peak at 573 cm −1 is related to a longitudinal optical (LO) scattering mode, due to doping of Mn 2+ ions. The doping of Mn 2+ on ZnO shows in noticeable shifts in phonon mode of Raman spectroscopy [48].…”

Through a facile chemical precipitation process, pure zinc oxide (ZnO) and various ratio of Mn-doped zinc oxide (Zn1-xMnxO) nanostructured materials were synthesized. The degradation of an azo dye acid orange 2 (AO-2) solution under UV light was investigated using the synthesized materials as photocatalysts. XRD, FTIR, DLS, FESEM, EDS, PL, BET, magnetic, TGA and UV-vis techniques were used to elucidate the structural, functional, particle, elemental, morphological, and optical aspects of the catalysts. The XRD and FESEM analysis showed the hexagonal ZnO structure and spherical shape of the ZnO nano-photocatalyst, respectively. Under UV irradiation for 60 minutes, MZ-25 NPs demonstrated better degradation (100.0%) of AO-2 dye. The effect of various factors such as catalyst quantity, and pH of the dye solution on the rate removal was investigated. After 60 minutes of UV light irradiation, dye removal was obtained under ideal conditions (with catalyst loading of 3 mgL-1, and pH 4).

This study investigates the synthesis and characterization of zinc oxide (ZnO) nanoparticles doped with 3% aluminum (Al) for photovoltaic applications. The ZnO nanoparticles were synthesized using the sol-gel technique and subsequently calcined at 400°C, 500°C, and 600°C. X-ray diffraction (XRD) analysis confirmed the formation of ZnO nanoparticles with a hexagonal wurtzite crystal structure. Transmission electron microscopy (TEM) and scanning electron microscopy (SEM) images revealed that the nanoparticle size increased with higher calcination temperatures. Energy-dispersive X-ray spectroscopy (EDX) confirmed the presence and homogeneous distribution of Zn, O, and Al within the samples. Fourier-transform infrared (FTIR) spectroscopy identified the presence of ZnO across all samples. Furthermore, the optical properties of the doped ZnO nanoparticles exhibited temperature dependent variations in absorbance, reflectance, and transmittance within the UV and Visible-IR spectra. The observed optical gap energies correlated with the calcination temperatures, suggesting a relationship between temperature, gap energy, and nanoparticle size. Overall, this study provides valuable insights into the synthesis and characterization of 3% Al-doped ZnO nanoparticles, emphasizing the significant influence of calcination temperature on their structural, morphological, and optical properties, which can be tailored for enhanced photovoltaic applications.
