Self-Assembled Dipole Nanolasers

摘要

Visible light excitation of silver nano-particles in the presence of polymerizable monomers and selected dyes triggers the self-assembly of nanolasers in a synthetically simple process. The new nanolasers incorporate a thin, fully organic gain medium that allows the tuning of the core absorption to a selected dye, or of the dye to a preselected core material. This versatile synthesis of surface plasmon lasers, or "spasers", has unique simplicity and enables spatial and temporal control of the nanolaser fabrication process.
