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.
Professor Julia Weinstein at the University of Sheffield has been a longstanding customer of Edinburgh Instruments’ and has established many successful collaborations with scientists across the globe. Her work concerns photo-induced charge and energy transfer reactions with applications in solar energy, bioimaging, and photodynamic therapy. We were lucky enough to get a chance to catch up with her, see what she had to say.
In this post we discuss the phenomena of second order diffraction through a monochromator and the problems it can cause in fluorescence spectroscopy. This is the second in a series of blog posts where we discuss the most common errors made, and experimental artefacts that appear when measuring fluorescence spectra. This list was originally inspired by the ‘Rogue’s Gallery of Fluorescence Artefacts and Errors’ in the excellent book ‘Introduction to Fluorescence’ by David M. Jameson.
Time Correlated Single-Photon Counting (TCSPC) is the method of choice for fluorescence lifetime measurements. This blog post follows an introduction to Time Correlated Single Photon Counting, which answers the question; What is TCSPC?
It has been another strong month for customer publications with over 240 research papers published using Edinburgh Instruments spectrometers in October. Here is a rundown of the top five publications from October.
In this blog post we highlight a recent paper by Professor Fiorenzo Vetrone, Small and Bright Lithium-Based Upconverting Nanoparticles (UCNP), which was published in JACS. In this paper a new synthesis route for small and efficient upconverting nanoparticles was reported and their properties optimised with the aid of an Edinburgh Instruments FLS980 Photoluminescence Spectrometer. The significance of Prof. Vetrone’s work and the photoluminescence techniques that they used to characterise their newly synthesised UCNPs are discussed.
The 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 between Luminescence, Photoluminescence, Fluorescence, and Phosphorescence”.
September was a fantastic month for Edinburgh Instruments customers with over 200 research papers published and many of these papers being published in high impact factor journals, including; Advanced Materials, JACS, and Nature. Here is a selection of some of the best from September.
In the first of a series of blog posts about common errors made, our applications team discuss how to identify the presence of Raman scattering during fluorescence measurements and how to prevent this scattering from distorting fluorescence emission spectra.
We are excited to share the first in an “Employee Spotlight” series from our Edinburgh Instruments, where we welcome new recruit and graduate, Peter Linton, who started at the beginning of August.
