Abstract
ABSTRACT Ultrasonic waves are called to hordes of mechanical waves that their oscillation frequency exceeds from human hearing range (20 Hz- 20 KHz). These waves have various applications due to their properties; ultrasonic frequency acoustic waves (16 KHz to 2 MHz) are used for curing and ultrasonic process parameters (amplitude, frequency and power) can be controlled properly. Ultrasonic process in fluids is followed by acoustic cavitation phenomenon (cavitation). Indeed, acoustic cavitation refers to the formation of bubbles (pores) due to the rapid drop in water caused by passing the sound waves through it. In this research, an action was made to produce CdSe and ZnS nanoparticles using this method. Ultimately, ZnS quantum dots and ZnS nanoparticles were connected to each other using a coupling agent copolymer (PEG-PCA). The optical properties of this nanoparticle were examined by using X-ray diffraction and evaluated using UV-Visblel range of coupling effect.
