Super-enhanced hyper-Raman scattering from dyes adsorbed on colloidal silver particles
Baranov A. V. , Bobovich Ya. S.
Hyper-Raman-scattering spectra have been measured by the standard technique for the scattering from two rhodamine dyes and a crystalline violet dye adsorbed or silver. The extremely intense spectra found are attributed, in particular, to simultaneous resonances for oneand two-photon transitions. Various mechanisms for the process are discussed. The same effects are observed at the unshifted frequency.
