    "abstract": "We have observed the compensation of loss in metal by gain in interfacing\ndielectric in the mixture of aggregated silver nanoparticles and rhodamine 6G\ndye. The demonstrated six-fold enhancement of the Rayleigh scattering is the\nevidence of the increase of the quality factor of the surface plasmon (SP)\nresonance. The reported experimental observation paves the road to many\npractical applications of nanoplasmonics. We have also predicted and\nexperimentally observed a suppression of the surface SP resonance in metallic\nnanoparticles embedded in a dielectric host with absorption.",
