Size distribution of the obtained silver nanoparticles for different values of the AgNO3 concentration. (A) 2.5 mM, (B) 5 mM, (C) 7.5 mM, and (D) 15 mM, and two reaction times (24 and 96 h). For clarity, we display the full histogram and a fit (green curve) for 96 h, but only the fit (black curve) for 24 h. Note the two populations for a reaction time of 96 h. The statistical analysis has been performed with more than 500 nanoparticles in each case.
