FINE-STRUCTURES OF RAMAN-SPECTRA OF LIF CLUSTER-BASED NANOFILMS

Raman measurements are carried out for LiF cluster-based nanofilms. Mu lti-order Raman scattering and surface modes are observed. Abundant Ra man peaks and conspicuous Raman bands which are composed of several pe aks are identified, and are discussed in terms of macroscopic and micr oscopic theories that have been used to describe the lattice dynamics of small crystals. Good agreement is achieved between the observed spe ctral peaks and the calculated results. Copyright (C) 1996 Elsevier Sc ience Ltd
