In this work, room-temperature UV-assisted ozone detection was investigated using ZnO nanoplates synthesized via precipitation, ultrasound-, ultrasonic tip-, and microwave-assisted hydrothermal (MAH) methods. X-ray diffraction confirmed the formation of crystalline phases with an ~3.3 eV band gap, independent synthesis used. Raman spectroscopy revealed oxygen-related defects. Plate-like morphologies were observed, tip-assisted yielding ~17 nm-thick plates. Electrical measurements showed 10–170 ppb sensitivity under UV. The sample MAH method (ZM) demonstrated superior conductance, a baseline resistance ~1.2% for ultrasound (ZU) less than 50% precipitation (ZA) tip (ZP) samples. Despite appreciable response in dark mode, recovery slow (>>30 min), except UV illumination condition, which reduced to ~2 min. With top areas ~0.0122 µm2, ZP ZU high specific surface (24.75 19.37 m2/g, respectively), contrast ZM, exhibited lowest value (15.32 m2/g) area ~0.0332 µm2 thickness 26.0 nm. performance ZM attributed larger nanoplate sizes lower resistance. due higher depletion layer effect. results indicate that methods presented herein production reactive NaOH as growth-directing agent are reliable, simple, cost-effective, addition being capable detecting reproducibility at concentrations low 10 ppb.
