Thermoplasmonics of micro glassbead coated with gold nanoparticles

The micro glass bead, which were covered by gold nanoparticles, was fabricated by wet process and studied for the plasmonic nano heater in water. The plasmonic beads of > 3 μm in diameter were thermally treated with electric oven for 3 hours. The thermoplasmonic bead generated plasmonic bubbles by laser illumination of the wavelength of 473 nm and the power of 32 mW.
