Paper Abstract

Photodecomposition by pulsed UV laser irradiation of metal acetylacetonate (MeAcAc) crystals which are embedded in polymethylmetacrylate (PMMA) films is investigated by scanning (SEM)- and transmission (TEM)- electron microscopy. The photodecomposition occurs at and above a laser fluence threshold of 50 mJ/cm2. Observations after irradiation performed under different condition, either in air or in vacuum, suggest that metal cluster formation develops in atmosphere upon PMMA ablation and MeAcAc decomposition. These clusters serve further as excellent catalytic centers for electroless metal plating, which develops at the irradiated sample surface.
