Spectral School

Why and how we fit components to recorded TCSPC data. Using a variety of examples, we show how different systems need to be explored in different ways from the same TCSPC system.

IR and Raman spectroscopy are two complimentary vibrational spectroscopy techniques. How to choose which one to use? Our Spectral School article explains how to tell if your samples are better suited to Raman or IR spectroscopy and why.

An introduction to Fluorescence Lifetime Imaging Microscopy (FLIM) and how it works.

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?

An introduction to Multi-Channel Scaling which is the ideal technique for identifying phosphorescent lifetimes.

In this Spectral School Tutorial, we introduce some of the most common optical microscopy terms and techniques, including upright and inverted microscopes, reflected and transmitted illumination modes, and brightfield and darkfield contrast mechanisms, and discuss their applicability with respect to different research areas.

A first introduction to the popular method of Time-Correlated Single Photon Counting which may be used to separate multiple fluorescence lifetimes from a single sample.

This poster presentation video illustrates how to fully characterise the photophysics of a Thermally Activated Delayed Fluorescence (TADF) material for OLED applications using an FS5 Spectrofluorometer. Spectral and time-resolved photoluminescence, quantum yield, and temperature dependence are all studied in a compact FS5 instrument.

In this Spectral School tutorial, we discuss the differences between the detectors available for Raman microscopes, and how to select one based on important performance parameters such as quantum efficiency and spectral range.

The FLS1000 Photoluminescence Spectrometer can be equipped with up to 5 different detectors (8 if two emission monochromators are present), and there is a wide range to choose from including analogue, high-speed detectors or NIR-sensitive photomultiplier tubes (PMTs). In this blog post we help you to select the best photomultiplier detector for your application, either when you first buy an instrument or when you are considering an upgrade.
