What is Laser Induced Fluorescence?

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.

COVID-19 Disease Testing; Utilising Fluorescence During a Pandemic

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

What is Resonance Raman Spectroscopy?

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.

Customer Publication: Nanoparticle Composites for Photoelectrochemical Water Oxidation

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.

What is Transient Absorption Spectroscopy?

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.

Frequently Asked Questions

How to choose your lasers for Raman spectroscopy

Which 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!

Investigating Efficiency Roll-Off in Quantum Dot LEDs (QLEDs) using the FS5 Spectrofluorometer

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.

What is Upconversion?

Photon upconversion is the sequential absorption of two or more long wavelength photons leading to the emission of a photon with a shorter wavelength.

What is Raman Spectroscopy?

What is Raman Spectroscopy? It is an analytical technique where scattered light is used to measure the vibrational energy modes of a sample.
