Plasmonic amplification of single exciton transitions in InGaN
- 38 Downloads
An increase in the rate of spontaneous recombination of excitons localized in films of InGaN solid solution due to interaction with a plasmon localized in a gold nanoparticle was experimentally observed. The particle is positioned near the surface with the help of a near -field scanning optical microscope or in the result of chemical precipitation from a colloidal solution. Precise positioning of a plasmonic particle allows single excitons with 1—2 meV-wide radiation lines to be revealed and amplified.
