In this study, photothermal bubble generation is demonstrated by using a near-infrared plasmonic absorber. A plasmonic nanopillar array is fabricated using a simple and low-cost soft thermal nanoimprint lithography process. Under near-infrared illumination, the plasmonic absorber becomes a highly efficient nanosource of heat because of enhanced light absorption at the localized surface plasmon resonance wavelength. The plasmonic substrate is able to generate size-tunable bubbles, depending on the illumination power and exposure time. The results of finite-difference time-domain simulations exhibit close agreement with the experimental observations. This study could provide alternative chemical synthesis approaches in solvothermal chemistry and sol-gel chemistry. |
