Abstract

Ag2O quantum dots highly versatile promising a wide range of applications from energy conversion to biomedicine making them an important area of research and development in nanotechnology. The tunibilty of the bandgab, make them highly suitable for optoelectronics device, LED, solar cell, were the band gab can be adjested by controlling the size of nanoparticles leading to different light absorbtion and emission properties. In this work, uniform and smooth quantum-sized silver oxide (Ag2O) nano-films were chemically prepared on a glass substrate using chemical bath deposition method. The study investigated the impact of interaction time before the deposition process, where the effect of three priod of time (0.5, 1 and 1.5) hrs on physical properties  have been invistigated. Structural analysis confirmed the cubic silver oxide (Ag2O) structure, corresponding to the primary diffraction plane (002). The optical results discuss the time dependency of the optical band gap, revealing an energy band gap of approximately 2.25 eV. The electrical conductivity initially shows an inverse relationship with time but increases after a certain point. Additional investigations were conducted on other properties, including electrical characteristics, Atomic Force Microscopy (AFM), and Scanning Electron Microscopy (SEM).

Highlights

Smooth Ag2O nanostructures were prepared using the CBD method. Interaction time affects optical band gap and particle size. The optimal band gap achieved was about 2.25 eV. Electrical conductivity varies inversely with interaction time initially. SEM and AFM analyses confirm uniform film characteristics.
