was fabricated through in-situ growth of silver particles with variant morphology on glass substrates by pretreatment electroless. The effect of surface morphology of thin films of silver nanoparticles on the SERS activity of the substrate was studied by SEM, XRD and UV-Vis spectroscopy. The results show that the morphology of silver nanoparticles changes with the change of the molar ratio of AgNO3......

AJITHA et al [16] investigated the preparation of silver nanoparticles... nm, indicating the formation of silver nanoparticles. This may be because AG can contribute more electronic density to the sp orbital of Ag+ and reduce Ag+ to silver particles. Therefore, AG plays......
