In this work, we develop a simple method to synthesize nanosized Ag colloids with the addition of hydrazine hydrate. UV–vis absorption spectra, dynamic light scattering (DLS) and transmission electron microscopy (TEM) have been used to trace the growth process and elucidate the structure of the silver nanoparticles. A solution in its UV–Vis absorption spectrum showed surface plasmon resonance absorption bands about 421 nm. We obtain silver colloids of average size 92 nm with a standard deviation of 30 nm after separation and washing procedures.
