Separation of Fluorescence and Light Scattering

Image of Separation of Fluorescence and Light Scattering

The Zhang Group discovered that both light scattering and fluorescence (not light scattering alone assumed in existing literature) can contribute to the resonance synchronous spectroscopy obtained with fluorescent samples. Presented is a ratiometric Bandwidth Varied Polarized Resonance Synchronous Spectroscopy (BVPRS2) method for separating fluorescence and scattering contributions. The ratiometric BVPRS2 signal from light scattering is independent of monochromator bandwidth, but fluorescence increases linearly with the monochromator bandwidth.
