Abstract

Two samples of Ag₂CrO₄ nanoparticles were synthesized by one step ultrasound-assisted method without requiring elevated temperature calcination process. The samples were characterized using XRD, SEM, TEM, FT-IR and UV-visible diffuse reflectance spectroscopy. The XRD results show that Ag₂CrO₄ is orthorhombic Ag₂CrO₄ phase and its morphology is nanoparticle. 1.45 eV and 1.95 eV are the optical band gap values for sample-A and sample-B respectively. In addition, a mechanism of Ag₂CrO₄ nanocrystals formation was also proposed according to the experimental results.
