What is the mechanism responsible for formation the small silver particles at high (pH ~8) and large agglomerated form at low pH (~3) from [AgNH3]2+?

Small nanoparticles with size below 6 nm were obtained at pH~8 (NaOH), particles with size up to 50 nm and agglomerated form were received at pH~3 (HNO3). The concentration of silver precursor and...
