The effect of two different capping-ligands (monoethanolamine (MEA) and oleylamine (OLA) as amino-additives) is studied using sol-gel route. Structural and morphological characterization techniques were used to quantify the particles size and molecular bonding. Results show that oleylamine as a chelating agent is more efficient in controlling the size of the as-synthesized nanoparticles, especially in low concentration of Ag⁺ precursor related to its long alkyl-chain preventing nuclei assemblage. This argument is confirmed by energy interaction calculation between Ag⁺ cations and oleylamine molecules using Molecular Dynamics Simulations. Finally, this investigation clearly demonstrates that the ratio between amino-additives (MEA and OLA) and Ag⁺ is the key-parameter that controls the crystalline growth of <span>Ag</span>₃<span>PO</span>₄particles thus leading to nanometric size. https://jns.kashanu.ac.ir/article_106195_771530514de030a4bc5b3b99d000456e.pdf
