A significant focus of the group’s research is the characterisation of the photophysical properties of a variety of samples, from solutions, thin films to bulk materials. We have a variety of instruments available to help us achieve this.
Edinburgh Instruments FLS1000 Photoluminescence Spectrometer
Performs steady state and time-resolved photoluminescence measurements- Wavelengths of available excitation sources are: 375 nm, 450 nm, 532 nm, 635 nm, 655 nm and 808 nm
- Sources at 532 nm, 655 nm and 808 nm can be operated as pulsed or continuous wave sources
- Various holders for liquid, solid and thin film samples as well as the capability to measure at cryogenic temperatures and a temperature-controlled cuvette holder (263 K – 378 K)
