Research Abstract

Absorption spectroscopy is useful for molecular identifications, while its sensitivity is limited by intensity fluctuation of light source and noises of a detector. In order to improve the sensitivity, miniaturization of the illumination area down to nanometer scale is promising since the absorbance is inversely proportional to the illumination area. In this study, to reduce the illumination area, local illumination of the apertured near-field probe was utilized. The near-field fiber probe was fabricated, and the operation principle for enhancing the sensitivity was examined. Absorption sensitivity was enhanced with this technique, and the improvement enables to obtain valuable spectroscopic information on nanomaterials with wide spectral range. . A single molecular sensitivity has not yet been achieved, however, by improving the fabrication of the near-field probe it will be realized in near future.
