“…The diffraction pattern for ZnO showed well-defined diffraction peaks, which are in good agreement with the hexagonal wurtzite structure and space group P63mc (JCPDS No. 36-1451) [24]. The high intensity and sharpness of the XRD peaks of the nanoparticles showed the high crystallinity of the obtained nanoparticles [25].…”

ZnO and TiO2 nanoparticles were prepared through a plant-extract mediated hydrothermal synthesis. X-ray diffraction (XRD) study confirmed the crystalline nature and the phase characteristic of the obtained nanoparticles. X-ray diffraction profile analysis models such as Williamson-Hall analysis, size-strain plot and Rietveld analysis were further used in evaluating the microstructural parameters of the obtained materials. The calculated particle size for all the models was in great agreement, with values in the range of 55.46-87.6 nm recorded for ZnO, while for TiO2, the crystallite size was in the range of 33.82-41.9 nm. The calculated crystal microstrain varied based on the model, while the stress in the ZnO and TiO2 nanoparticles was evaluated at 3.8 and 13.7 MPa, respectively. Furthermore, TiO2 nanoparticles had a higher energy density of 8.96 × 10-8 KJ/m3 compared to 7.12 × 10-8 KJ/m3 obtained for ZnO.

This paper presents ultrafast response, self-powered UV photodetectors (PDs) based on ZnO/SiO2/Si heterojunction diodes, utilizing zinc oxide (ZnO) nanorods as the photosensitive layer. This configuration results in photodetectors exhibiting unprecedentedly rapid response times, with rise and decay times reduced to 440 ns and 320 ns, respectively. Our study, focusing on ZnO nanorod PDs, not only demonstrates ultrafast response times but also highlights the role of hydrothermal synthesis temperature in tuning the devices' performance. These findings represent a significant leap forward in the development of high-performance, self-powered UV PDs. The effects of different temperature hydrothermal on the morphology, crystal structure, and optoelectrical properties were systematically investigated using various characterization techniques, including field-emission scanning electron microscopy (FE-SEM), energy dispersive X-ray analysis (EDX), X-ray diffraction (XRD) analysis, photoluminescence analysis, and current-voltage (I-V) measurements.
