摘要：

In this work, a photo-induced method for obtaining silver nanoparticles (SNPs) was investigated using UV LED, xenon lamp and sodium lamp excitation. Silver colloidal solutions were prepared using autopolymerizable resin and AgNO3 in an ethanol solution. This study shows that the combination of pulsed laser ablation in liquids with previous UV-visible illumination provides a simple, applicable and flexible technique for the fabrication of nanoparticles of 5-8 nm in size.
