Crystalline silver thin layers were obtained by high-energy pulsed laser ablation without heating of the deposition substrate. The fluid Plateau-Rayleigh (PRI), Rayleigh – Taylor (RTI) and Richtmyer Meshkov (RMI) instabilities, as well crown splash induced during (PLD) in high energy regime, resulting ring pearl shaped structures, offer benefit increased sorption surface. These morphological structures for make them interest catalytic applications. study presented with this work addresses both fundamental applied issues on layer their function organic processes. In sense, action was highlighted modifications Reactive Blue 21 dye (C.I.) aqueous solution sodium bicarbonate. Specific investigations analyzes carried out electron microscopy elemental analysis (SEM-EDX), atomic force (AFM) profilometry, mass spectrometry, plasma diagnosis, diffractograms (XRD), IR spectroscopy (FTIR). addition to experimental investigation analyzes, simulation ionization threshold conducted COMSOL complementary evaluation involved processes phenomena.
