Resumen:
We report the enhancement of the optical second harmonic signal in non-centrosymmetricsemiconductor CdS quantum dots, when they are placed in close contact with isolatedsilver nanoparticles. The intensity enhancement is about 1000. We also show that theenhancement increases when the incoming laser frequency w is tuned toward the spectralposition of the silver plasmon at 2w, proving that the silver nanoparticle modifies thenonlinear emission.
