In this application note, we demonstrate how transient absorption spectroscopy and temperature-dependent measurements can be employed to investigate and understand the nature of photoexcited triplet states of a molecule.

Surfaced enhanced Raman scattering (SERS) is an enhancement technique in which nanoparticles are used to provide Raman intensity enhancement. In this application note the optimisation of gold nanoparticles are investigated for the development of a SERS glucose sensor.

Featured in the prominent Science Advances journal, this exceptional research into intramolecular Förster-type triplet-to-singlet energy transfer in a donor-bridge-acceptor (DBA) dyad was led by Prof. Karl Börjesson at the University of Gothenburg and team of researchers across Sweden utilising Edinburgh Instruments FLS1000 and LP980 Spectrometers.

Researchers from Birmingham University have developed a new complex for DNA sensing in collaboration with Edinburgh Instruments. Find out how our FLS1000 Spectrometer was used in this research.

The ideal anticancer drug would be one that is effective at killing rapidly producing cells, is targeted directly to the tumour location, and is non-toxic until it reaches the diseased area. Platinum-II (PtII) based chemotherapy drugs have been life changing for many, with the most common drug, Cisplatin, providing treatment and cures for cancerous diseases in the bladder, breast, cervix, lung, ovaries, and head and neck, to name a few.

Understanding and optimising novel materials for the next generation of fuel sources for our energy needs that are efficient, affordable, and carbon neutral is of paramount importance for generations to come. Photocatalytic materials that can harvest sunlight and generate hydrogen gas (H2) from water is highly sought after given the enormous energy released and environmentally friendly by-product of water when burning this gas for energy.

In this application note, the measurement of sub 20 picosecond lifetimes utilising the FLS1000 Photoluminescence Spectrometer equipped with a hybrid photodetector is demonstrated, and the impact that the configuration of the FLS1000 has on the minimum lifetime that can be measured is discussed.

In this technical note we explore Transient absorption (flash photolysis), which is a powerful tool to understand many photochemical properties and reactions, from measuring the energy levels and lifetimes of excited singlet and triplet states, to measuring electron and energy transfer rates of paired molecular systems, and even photocatalysis intermediates and products.

This customer written application note describes how to measure the two-photon absorption spectra of fluorescent chromophores by using an external short-pulsed laser source in an Edinburgh Instruments FS5 Spectrofluorometer. A procedure on how to calculate the nonlinear refraction dispersion from the measured spectra is also given.

Researchers in Fujian, China, led by Rong Cao and Zu-Jin Lin, have developed a new method for sensing ClO- employing fluorescence spectroscopy and novel metal organic frameworks. The authors used an Edinburgh Instruments FS5 Spectrofluorometer to characterize and optimise the sensor’s response towards ClO- . They then employed this sensor to detect ascorbic acid, an essential nutrient for the human body.
