in this article we offered a method for improving the ratio of signal to fluorescence in Raman spectroscopy based on photobleaching. It was demonstrated to be a simple approach to remote reduction and suppression the magnitude of the fluorescent background reduced exponentially with time. Pre-exposure to laser light significantly reduces sample autofluorescence, but minimally affects Raman signals. We demonstrated the capability of this method for Raman spectral measurements of acetaminophen tablets.
