摘要

The wet chemical preparation approach was used to synthesize both pure and W-doped ZnO material. The resulting crystalline phase, lattice parameters, and average grain sizes were rigorously analyzed using X-ray diffraction (XRD) techniques. Field emission scanning electron microscopy (FESEM) revealed the distinct nanoplates morphology of the synthesized materials. Optical properties, such as the UV cut-off wavelength and bandgap, were determined through UV-Vis spectroscopy. Electrical evaluations involved using an LCR meter for dielectric analysis and a piezometer to measure the piezoelectric charge coefficient (d33). Piezoelectric voltage outputs were further tested under mechanical tapping at 10, 20, and 30 Hz. This study ultimately demonstrates that W-doping significantly enhances the ferroelectric characteristics of ZnO nanoplates.
