Abstract:Based on the scanning of photothermal optical coherence tomography (PT-OCT), the photothermal behavior of a flowing medium generated by the enhanced absorption of localized surface plasmon resonance of incorporated Au nanorings (NRIs) is observed. In particular, the effects of air bubble generation and thermally induced bubble size oscillation in a flowing medium through the incorporation of Au NRIs and modulated laser illumination are demonstrated. The size oscillation of the air bubble produces the vibration… Show more
