Summary:We designed a zinc oxide (ZnO) growth device using a cylindrical piezoelectric lead zirconate titanate (PZT) vibrator. This growth device can be employed to realize a simpler and more efficient synthesis method using focused ultrasound. To confirm the effectiveness of the device, the distribution and nanostructure size were investigated under different ultrasonic powers and precursor concentrations. The size of the synthesized nanostructure was proportional to the precursor concentration and ultrasound intensity. The chemical effect of the ultrasound is more dominant than the mechanical one when the ultrasonic cavitation is generated. According to the results of the X-ray diffraction pattern and distribution, the synthesized nanostructure showed a high crystallinity and a populous distribution at the target area.
