What is the Stokes Shift?

Stokes Shift, named after Irish physicist George Gabriel Stokes, is the term given to the spectral shift to lower energy between the incident light and the scattered or emitted light after interaction with a sample. The Stokes Shift is an important concept in both Fluorescence and Raman spectroscopy and is introduced in this article.

Choosing Detectors for your FLS1000 Photoluminescence Spectrometer

The FLS1000 Photoluminescence Spectrometer can be equipped with up to 5 different detectors (8 if two emission monochromators are present), and there is a wide range to choose from including analogue, high-speed detectors or NIR-sensitive photomultiplier tubes (PMTs). In this blog post we help you to select the best photomultiplier detector for your application, either when you first buy an instrument or when you are considering an upgrade.

Emission Correction in a Fluorescence Spectrometer

When fluorescence spectra are measured in Edinburgh Instruments fluorescence spectrometers, two types of correction can be applied to the spectra; excitation and emission correction. In this blog post we focus on the role of emission correction and discuss why it is required, how it is implemented, and the effect it has on the shape of fluorescence spectra.
