Abstract

We propose a method for separating fluorescence and Raman spectra in UV region using classical least squares. The method was applied to highly fluorescent samples. Since the spectral decomposition is based on many spectral data with different intensities, the fluorescence and Raman spectra were successfully resolved. As a result, the method effectively reduced the fluorescence interference in Raman spectral measurements.
