ABSTRACT
We report on the observation of spectrally narrowed emission (SNE) from rhodamine 6G infiltrated in synthetic opals, and the enhancement of the spectral narrowing by the surface plasmon resonance effect of Ag particles anchored on the internal surface of the opals. With Ag particles, SNE is observed at a lower pump intensity, and the threshold of the spectral narrowing is one-tenth lower than that without Ag. It was clarified that enhancement is not caused by the light scattering of the Ag particles, but by the surface plasmon resonance. © 2003 American Institute of Physics.
