Analysis of nucleation and growth parameter of silver nanoparticles for sensors

Synthesis of Silver nanoparticles using silver nitrate as metal salt precursor and citric acid as reducing agent is being reported in this paper. Using Spectroscopy, silver nanoparticles nucleation and growth parameter has been analyzed. Absorption spectra of silver nanoparticles in water are determined. Absorption spectra shows two absorption peaks while crystal was growing, whereas fully grown crystal shows single absorption peak confirms heterogeneous crystal growth in liquid medium and average size distribution of silver nanoparticles.
