Influence of solvents on the morphological properties of AgBr nano-structures prepared using ultrasound irradiation

Nano-structures of AgBr have been prepared by reaction between AgNO3 and KBr under ultrasound irradiation. Particle sizes and morphology of nanoparticle are depending on temperature, power of sonicating, reaction time and concentration. The effects of these parameters in growth and morphology of the nano-structures have been studied. Results suggest that an increasing of temperature, sonication power and concentration led to a decreasing of particle size. The samples were characterized with powder X-ray diffraction (XRD) and scanning electron microscopy (SEM).

► Nano-structures of AgBr were prepared under ultrasound irradiation.
► Particle sizes of nanoparticle are depending on temperature, sonication power, reaction time and concentration.
► These systems depicted a decrease in the particles size accompanying an increase in the temperature and sonication power.
► Results suggest that a decreasing of concentration leads to an increasing of particle size.
