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.

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.

Application Note: Study of Fluorescence Quenching Kinetics Using Stopped-Flow

A powerful method for determining the kinetics of a reaction is by monitoring the concentration of the reactants or products over time using stopped-flow fluorescence spectroscopy. In this application note, the kinetics of NATA quenching by QBS are determined using the FLS1000 Photoluminescence Spectrometer equipped with the stopped-flow accessory.

Application Note: Plastics Identification Using ATR-FTIR Spectroscopy

Plastics are widely used daily and are among the primary pollutants on the planet. A solution to prevent environmental pollution due to plastics is to identify their type and dispose of or recycle them appropriately. ATR-FTIR is a simple and robust spectroscopic technique that enables rapids plastics identification based on the characteristic IR spectrum of each sample. In this application note, an Edinburgh Instruments IR5 FTIR Spectrometer was used to identify four different plastic samples successfully.

Application Note: ATR-FTIR of Blood Serum Using a Heated ATR Accessory

This application note demonstrates the use of ATR-FTIR spectroscopy for the analysis of human serum albumin. An IR5 FTIR spectrometer was used, equipped with a heated ATR accessory, to help tackle the issue of strong water absorption bands masking the IR bio-spectrum.

Application Note: Kinetics of Persistent Luminescence Phosphors

Persistent luminescence, commonly called afterglow, is long-lasting visible emission over several hours after ultraviolet excitation. It has many applications; ranging from glow-in-the-dark signage to in-vivo imaging for disease diagnosis and treatment. In this application note, the persistent luminescence kinetics of a doped strontium aluminate phosphor are characterised using the FLS1000 Photoluminescence spectrometer

Application Note: UV-Vis Spectroscopy for Characterising the Optical Properties of Gold Nanoparticles

UV-Vis spectroscopy is routinely used in analytical science in part because it is a simple way of studying a sample’s optical properties over the UV and visible regions of the electromagnetic spectrum. Here, we used the DS5 UV-Vis Spectrophotometer to study the unique and interesting effects that occur when gold nanoparticles interact with light. Read to find out more.

Application Note: Characterisation of SERRS Nanoparticles Using UV-Vis and Raman Spectroscopy

Surface-enhanced resonance Raman scattering (SERRS) is a technique that offers unparalleled sensitivity and specificity in spectroscopic detection and is promising for many applications in analytical research. In this new Application Note, we use the DS5 UV-Vis Dual Beam Spectrophotometer and RM5 Raman Microscope to demonstrate that the optical response of SERRS nanosensors contains combined SERS and RRS effects.

Application Note: Photoluminescence of Lanthanide-based Optical Probes

Optical probes based on lanthanide complexes are of particular interest in the biomedical field and life sciences due to their unique magnetic and photoluminescent properties. In this application note, an Edinburgh Instruments FS5 Spectrofluorometer is used for a complete characterisation of the lanthanide-based optical probes.

Application Note: High-Resolution Raman & Photoluminescence Imaging of MoS2

In this application note, the transition-metal dichalcogenide molybdenum disuflide (MoS2) is characterised using the RM5 Confocal Microscope with Raman and photoluminescence imaging to characterise its layer-dependent optoelectronic properties.
