ABSTRACTWe report results of Raman spectroscopy of size selected, matrix isolated Si clusters. Cluster ions produced by laser vaporization are size selected by a quadruple mass spectrometer and co-deposited with cryogenic matrices onto a substrate at ∼15K. A surface-plasmon-polariton-enhanced Raman geometry is used to gain adequate signal.The observed vibrational frequencies from Si4, Si6 and Si7 are compared with theoretically calculated Raman active modes based on the structures of planar rhombus, distorted octahedron and pentagonal bipyramid, respectively. The agreement is excellent. Cluster agglomeration is observed when cluster concentrations exceed ∼0.3% by volume in the matrix and/or with annealing at ∼28K, below the temperature of matrix evaporation.

Metal nanoparticles have the ability to localize and strongly enhance the incident electromagnetic field due to the surface plasmon polariton. The coupling between AuNPs and ZnO thin films affects their emission properties. In this study, we prepared the ZnO / Al 2 O 3/ AuNPs multilayer films, and investigated the effect of spacer layer on enhancement and quenching of photoluminescence by surface plasmon. The emission intensities of the thin films vary when Al 2 O 3 space layer with different thickness was embedded in the ZnO / Au films, consistent with theoretical predictions. The photoluminescence modulation is also made via controlling the polarization of the excitation source. The photoluminescence anisotropy of these systems shows that enhanced photoluminescence can be achieved through coupling of the emission from ZnO with the surface plasmon resonance of AuNPs .
