We are delighted to announce that we will be running a series of webinars in June covering molecular spectroscopy applications. The webinars are open to anyone interested in expanding their knowledge on current research topics and trends in fluorescence, Raman and transient absorption spectroscopy. Browse the series and register your interest.
Laser Induced Fluorescence (LIF) is an optical spectroscopic technique where a sample is excited with a laser, and the fluorescence emitted by the sample is subsequently captured by a photodetector. LIF can be understood as a class of fluorescence spectroscopy where the usual lamp excitation is replaced by a laser source. Find out more.
While the world continues to endure loss and hardship due to the outbreak of COVID-19, caused by a novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), researchers are scrambling to provide test kits that are accurate, fast, sensitive, and widely available, especially as symptoms vary broadly and may not appear for days if at all. To this end, several diagnostic
Resonance Raman spectroscopy is a Raman enhancement technique in which the laser excitation frequency is chosen to be close to the frequency of an electronic transition of the sample. Resonance Raman can enhance the Raman scattering intensity by a factor of 102-106 and improves signal-to-noise. Find out more.
We were delighted to see the recent publication by Dr Stoichko Dimitrov, Lecturer in Chemistry at Queen Mary University of London, on Nitrogen-Doped Carbon Dots/TiO2 Nanoparticle Composites for Photoelectrochemical Water Oxidation.
Transient absorption (TA) spectroscopy, also known as flash photolysis, is a pump-probe spectroscopic technique utilised to measure the photogenerated excited state absorption energies and associated lifetimes of molecules, materials, and devices. Find out more.
In this fascinating read we take a look at the work of our Application's Team and Dr Gianluca Accorsi, a Research Fellow at CNR Nanotec in Lecce, Italy, who carried out research on the photo-physical properties of Egyptian blue pigment using our Fluorescence Spectrometers. Find out more.
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!
Quantum dot light emitting diodes (QLEDs) have attracted immense research interest from both academia and industry due to their desirable display properties. The linewidth of the emission from quantum dots (QDs) is significantly narrower than from organic molecules which means that QLEDs can potentially offer displays with higher colour gamut than OLEDs.
Photon upconversion is the sequential absorption of two or more long wavelength photons leading to the emission of a photon with a shorter wavelength.
