Abstract

Due to the difficulties in geometrical arrangement, up to now the polarization arrangement for waveguide Raman spectroscopy (WRS) was limited to only a few simple configurations. In this report, we present the experiments in extending polarization configurations for WRS. The resulted polarized WRS spectra of thorium phosphate xerogel thin films will be presented. In the region of Raman shift from 850 to 1200 cm-1 ,two components with different polarization behavior exist. Based on the symmetry arguments, these components are then identified to the different vibration modes of P043 ions. From the spectra it is also concluded that the film is amorphous and isotropic and has chain-like structure.
