Photobleaching profile of Raman peaks and fluorescence background

15 December 2017 | By , , , ,

Laser-induced fluorescence is the most common source of interfering baseline signal encountered in Raman measurements. It shows itself as a slowly changing background in a spectrum. One of the challenges in the successful use of Raman spectroscopy is to extract Raman signatures from this, orders of magnitude stronger, broadband fluorescence…
