Application Note: Observing Phase Transitions in a Halide Perovskite Using Temperature Dependent Photoluminescence Spectroscopy

Perovskite photovoltaic cells are exposed to a wide range of temperatures and it is therefore important to understand the influence of temperature on the properties of the perovskite. In this application note, the FLS1000 spectrometer equipped with the liquid nitrogen cryostat accessory is used to determine the phase transition temperatures of MAPI perovskite.

Feature Highlight: MicroPL Upgrade

The MicroPL Upgrade for the FLS1000 and FS5 photoluminescence spectrometers enables widefield imaging, single point spectra and lifetime, and lifetime imaging of microscopic photoluminescent samples.

Application Note: Temperature-Dependent Quantum Yield of Chlorophyll Fluorescence in Plant Leaves

Fluorescence spectroscopy is a powerful tool to investigate the photochemistry of biological systems. In this application note the influence of temperature on the photochemistry of perennial leaves is investigated by measuring the fluorescence quantum yield over a temperature range of 77 K to 300 K using the FLS1000 equipped with the Cryosphere accessory.

Detectors for Raman Spectroscopy: CCDs, EMCCDs, and InGaAs Arrays

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.

Choosing Detectors for your FLS1000 Photoluminescence Spectrometer

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?

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.

Relative Quantum Yield

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.

What is Fluorescence Lifetime?

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

What is FTIR Spectroscopy?

This quick read blog will introduce the basics of FTIR spectroscopy discussing how the instrument works, and what the resulting spectrum can reveal about your sample.

Common Sampling Techniques of FTIR Spectroscopy

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
