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.

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.

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.

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.

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.

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

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.

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.

Surfaced enhanced Raman scattering (SERS) is a great technique to enhance the Raman scatter from a sample. One application SERS is well suited to is testing for the presence of pesticides on apple skin. This is important for keeping produce safe for consumptions, as well as monitoring the environmental impact of using pesticides.

In this application note, the transition-metal dichalcogenide tungsten diselenide (WSe2) is characterised using the RMS1000 Confocal Microscope with five imaging modalities: reflected brightfield & darkfield, Raman, photoluminescence and second harmonic generation to fully characterise its layer-dependent optoelectronic properties. The multimodal capabilities of the RMS1000 Confocal Microscope make it an ideal imaging platform for studying the optoelectronic properties of transition-metal dichalcogenides.
