Abstract
The application of Raman microprobe spectroscopy for the analysis of the gas contents in bubbles in glass was studied in terms of various aspects of the applied experimental procedure. The rotational Raman spectra of bubbles for various gases in the bubbles could be measured with good sensitivity. The Raman microprobe spectra for small bubbles (less than 30 μm diameter) could be measured with good signal-to-noise ratios. The possibility of applying this technique to the quantitative analysis of gas contents in bubbles was examined. The importance of the cleaning procedure for the glass materials during bubble preparation was also discussed in terms of controlling the gas contents in bubbles that will be used for systematic heat treatment investigations.
