3.2. Effect of silver nitrate concentration
Yellowish brown and light reddish brown colors were
observed at salt concentrations of 0.25 and 0.5 mM, and darker
shades of reddish brown color were observed at silver nitrate
concentrations ranged from 1.0 to 2.0 mM. The SPR peak of
silver nanoparticles became distinct with increasing the
concentration of silver nitrate, the maximum peak intensity
was obtained at 1.75 mM of AgNO3 (Fig. 1b). A variation in the
biological material and metal salt concentration is known to
influence nanoparticle synthesis (Pimprikar, Joshi, Kumar,
Zinjarde, & Kulkarni, 2009).
