The quantum yield of a material is a fundamental photophysical parameter that defines its efficiency to convert absorbed light into emitted and can be measured optically using either the relative or absolute method. This blog post focuses on the underlying theory of the relative method and explains how to measure it by using the Edinburgh Instruments FS5 Spectrofluorometer.
Is this our strongest Map of the Month yet? Graphene is one of the strongest materials known to man, and Raman mapping is a fantastic analysis tool for investigating any defects that might destroy this strength.

We are lucky to have some holly just outside our factory in Scotland which makes us feel Christmassy all year round. Taking advantage of this we have measured the fluorescence quantum yield of its leaves as a function of temperature, using an FLS1000 with a Cryosphere accessory.
We would like to thank all our customers and partners and wish you all a happy holiday season, and a joyful new year. We look forward to working with you in 2022.
With Christmas fast approaching our Map of The Month features one of the most used types of Christmas Tree – the pine tree! Find out more about this FLIM image of a pine tree section taken on our RMS1000 Raman Microscope.
With the holiday season fast approaching, we have a wonderful festive competition for you. Enter now!
Manufacturers of bank notes will use specific and unique dyes which helps keep authentic bank notes in circulation and aids the identification of forgeries. The dyes will have different photoluminescence (PL) emission, excitation, and lifetimes which can be used for authenticity checks.
Chandrasekhara Venkata Raman, the man responsible for discovering the Raman effect, paved the way for the modern Raman Microscopes that Edinburgh Instruments manufactures today. In honour of his birthday, we take a look into the path that led to the scattering discovery and all achievements thereafter.
Welcome to Edinburgh Instruments newest blog celebrating our work in Raman, Photoluminescence, and Fluorescence Lifetime Imaging. Every month we will highlight our pick for Map of the Month to show how our spectrometers can be used to reveal all the hidden secrets in your samples.
Blood can also tell us a lot about our own body’s health. It is the fluid that circulates around our body providing nutrients, oxygen, and waste removal. The best way to analyse blood via Raman spectroscopy is by analysing the plasma or the serum. Find out more in this fascinating read.
