Spectral School

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.

What is Quantum Yield? In this article we give a useful insight to the history of quantum yield and how to measure it using the Absolute and Relative methods.

The quantum yield of a material is a fundamental photophysical parameter that defines its efficiency to convert absorbed light into emitted and can be measured optically using either the relative or absolute method. This blog post focuses on the underlying theory of the relative method and explains how to measure it by using the Edinburgh Instruments FS5 Spectrofluorometer.

Fluorescence lifetime is an important photophysical parameter, providing insights into the energy relaxation and dynamics of the species under study.

FTIR spectroscopy can be configured with multiple sampling accessories covering all applications. This article introduces the most commonly used sampling techniques; transmission, ATR, specular reflectance, and DRIFTS. Learn about how each technique works, its most important applications areas, and the pros and cons of using them in your research

Raman Poster Presentation Series – Food Analysis using Raman Microscopy. This short video discusses some applications of Raman microscopy in the foods & drinks industry: detection of pesticides, identification of edible oils, ethanol and methanol testing of whisky, and chocolate distribution analysis.

In this technical note, the Fourier Transform Photoluminescence (FT-PL) accessory in the IR5 FTIR Spectrometer is used to characterise the mid-infrared photoluminescence of a lanthanide-doped sample. The FT-PL results are compared with data obtained by a scanning PL spectrometer.

Our team have put together a description on the inner workings of fluorescence spectrometers, and have provided a basic guide on fluorescence.
