▎ 摘　　要

The light-matter interaction between nitrogen-doped graphene quantum dots (N-GQDs) and bismuth telluride (Bi2Te3) nanoplates is investigated. A maximum of (2.9 +/- 0.3)-fold emission rate enhancement is observed at room temperature due to the coupling of N-GQD emission with the breathing mode of surface plasmon of single Bi2Te3 nanoplates. The enhancement varies with different emission wavelengths and nanoplate diameters in accordance with results obtained through the dipole radiation power in the electromagnetic simulations. From experiment, the quantum yield of N-GQDs is obtained to be almost unity, while Bi2Te3 nanoplates may replace the conventional antenna. Such combination of novel active and plasmonic materials is promising for efficient lighting applications with multiple functionalities, especially tunable plasmonic metamaterial based on topological insulators.
