Study the evaluation of Williamson–Hall (W-H) strain distribution in silver nanoparticles prepared by sol-gel method

In current study, Silver nanoparticles were prepared by Sol-Gel Method using Ag (NO3).3H2O as a precursor and a citric acid as a fuel. The nanoparticles of Silver were prepared at several of temperatures’ calcination of (as prepared, 300, 500, and 700°C). Three of Williamson-Hall models, namely model of Williamson-Hall uniform deformation (UDM), model of Williamson-Hall uniform stress deformation (USDM) and Williamson-Hall and model of Uniform deformation energy density (UDEDM), have been used to estimate some of the parameters of the microstructure like the deformation stress (σ), strain (ε), crystallite size (D) and deformation energy density (U) from X-Ray Diffraction data of silver nanopowder.
