Lanthanide-doped upconversion nanoparticles (UCNPs) are attractive luminescent materials for nanophotonic applications under near-infrared excitation, but their full potential is still limited by the low quantum yield of upconversion emission. Herein, we have designed and demonstrated a strategy to enhance the emission of a UCNPs film by a laser-induced microbubble. The microbubble plays multifunctional roles, including collecting plasmonic Ag NPs from the solution by the Marangoni convention, printing them on the UCNPs film to enhance the emission by localized surface plasmon resonances, and serving as a bubble microresonator to enable optical whispering gallery modes (WGMs). Together, the bubble microresonator along with plasmonic Ag NPs can enhance the upconversion emissions by over 200 times. This integrated approach opens new pathways for simultaneous enhancement of emissions from luminescent materials and assembly of NPs over desirable surfaces for optomechanical, biochemical, and sensing applications.
