The Optical Qualities of a Solution Made of Copper-doped Silver Sulfide Colloidal Nanoparticles

Abstract

The researchers present new optical properties of Cu-doped Ag₂S colloidal solution synthesized via a wet chemical method. They investigate the effects of doping on nanoparticle properties. TEM images reveal spherical samples with sizes ranging from 6 to 18 nm. Doped samples exhibit a redshift in absorption spectra compared to pure Ag₂S. Additionally, Pl intensity decreases with increasing Cu concentration. Size estimation from absorption spectra aligns with TEM results, with slight variations. This study unveils the unique optical characteristics of Cu-doped Ag₂S colloidal solution, shedding light on the impact of doping and providing valuable insights into nanoparticle behavior and synthesis techniques.
