Congratulations to our customer, Professor Arjan J. Houtepen and his research group at Delft University of Technology, who recently had their paper “Finding and Fixing Traps in II−VI and III−V Colloidal Quantum Dots: The Importance of Z‑Type Ligand Passivation” published in JACS. In this research highlight we will discuss the importance of Prof. Houtepen’s work on colloidal quantum dots and the photoluminescence (PL) spectroscopy techniques that were used in their recent paper.
In the broadest sense a spectrometer is any instrument that is used to measure the variation of a physical characteristic over a given range; i.e. a spectrum. The most ubiquitous type of spectrometer used for research are optical spectrometers; and when someone simply says ‘spectrometer’, without an additional qualifier, they are usually referring to an optical spectrometer and this diverse family of spectrometers is the focus of this article.
The new year is off to a strong start for customer publications with over 250 papers published using Edinburgh Instruments spectrometers during January. Here is a selection of the highlights from last month.
We were delighted to talk to Prof. Hanson from Florida State University to find out about his work in the field of photophysics research and how he has been using our FLS1000 Photoluminescence Spectrometer and LP980 Transient Absorption Spectrometer.
There was no slowing down Edinburgh Instruments’ customers during the festive period with over 170 papers published using our fluorescence and transient absorption spectrometers in December. Here is a breakdown of some of the best from last month.
In the 2nd of our Employee Spotlight Series we sit down with Optical Alignment Engineer, Ivan Rybtsov and talk about his role at Edinburgh Instruments as well as where his passion for science comes from.
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.
