✦ Synopsis

The photochemical synthesis of Ag(0) nanoparticles in the presence of amino-and carboxylate-terminated PAMAM dendrimers is reported. The formation of Ag(0) nanoparticles was followed spectrophotometrically and by transmission electron microscopy (TEM). According to TEM investigations Ag(0) nanoparticles with the average size of about 7 nm in diameter were produced. Based on the present investigation a possible mechanism for the Ag(0) nanoparticles formation is proposed.

## Abstract G5.0‐OH PAMAM dendrimers were used to prepare fluorescent silver clusters with weaker ultraviolet irradiation reduction method, in which the molar ratio of Ag^+^ to PAMAM dendrimers was the key factor to determine the geometry and properties of silver nanoparticles. The results showed t
