Direct Visible Spectral Analysis of Solid Samples by Optical Waveguide Spectroscopy due to Adsorbed Sample Molecules after Sublimation

摘要

Visible spectra of solid samples were obtained by optical waveguide (OWG)spectroscopy.The spectra were confirmed to be due not to the powder samples themselves but to molecules sublimed from the solid samples and adsorbed on the waveguide.This result is supported by the observation that no spectrum was obtained from nonsublimed samples.
