摘要: This work reports on the optical response and morphological changes of gold nanoparticles (NPs) induced by laser irradiation with single nanosecond pulses different fluences wavelengths. The as-grown specimens consist irregularly shaped NPs (10–13nm in average dimensions) produced pulsed deposition a substrate. They exhibit broad absorption band related to surface plasmon resonance (SPR) peaking range 634–685nm. After above threshold value, blueshift, decrease overall absorption, narrowing SPR are observed. peak wavelength amplitude after at increasing reach an approximately constant irrespective wavelength. value is consistent homogeneous distribution spherical mean diameter close initial dimensions as determined transmission electron microscopy. results demonstrate that conversion o...
