Frequently Asked QuestionsWhat is Quantum Yield? In this article we give a useful insight to the history of quantum yield and how to measure it using the Absolute and Relative methods.
Frequently Asked QuestionsWhich lasers do you need for Raman spectroscopy? Exploring the positives and negatives of the three laser regions used in Raman spectroscopy: UV, visible, and near-infrared, we review the considerations to be made for optimising a Raman system to your application needs!
Frequently Asked QuestionsWhen fluorescence spectra are measured in Edinburgh Instruments fluorescence spectrometers, two types of correction can be applied to the spectra; excitation and emission. In our previous blog post, we focused on emission correction and its role in the detection system. Now we turn our attention to excitation correction.
Frequently Asked QuestionsThe Jablonski Diagram is widely used in fluorescence spectroscopy to illustrate the excited states of a molecule and the radiative and non-radiative transitions that can occur between them.
Frequently Asked QuestionsThe terms; luminescence, photoluminescence, fluorescence and phosphorescence are routinely used in research papers to describe the emission of light from a sample. This multiple naming can be confusing with several of the terms being used interchangeably and researchers from different scientific backgrounds preferring to use one name over another. In this article we answer the question, "What is the Difference
Frequently Asked QuestionsTime-correlated single-photon counting (TCSPC) is a well established and common technique for fluorescence lifetime measurements, it is also becoming increasingly important for photon migration measurements, optical time domain reflectometry measurements and time of flight measurements.
Frequently Asked QuestionsFluorescence spectroscopy is a widespread analytical technique, but dealing with unknown samples can often be challenging even for experienced users. Our team have put together a procedure for spectral measurements to help newcomers in the fluorescence spectroscopy field.
Frequently Asked QuestionsAcquiring and interpreting steady state fluorescence data is not always straightforward. Below we offer some advice on commonly encountered problems to help you optimise the operation of your Edinburgh Instruments spectrometer.
Frequently Asked QuestionsThe inner filter effect is a common problem in fluorescence spectroscopy, affecting spectral measurements in particular. Our team has come up with a solution to this.
Frequently Asked QuestionsOur team have put together a description on the inner workings of fluorescence spectrometers, and have provided a basic guide on fluorescence.
