Project Description
Photoluminescence quantum yield is a measure of a material’s ability to emit light. Materials with high quantum yields are crucial for a wide range of applications including; lighting, displays, lasers, bioimaging probes and next-generation solar cells. The accurate determination of quantum yields is vital for continued advancements in these areas.
In this project, you will investigate novel approaches to improve the science of quantum yield determination. Photoluminescence quantum yields are widely reported in the scientific literature but routinely suffer from low accuracy due to calibration errors and a lack of practical standards to validate the results. The aim of the project is to improve the accuracy and reliability of quantum yield measurements, particularly in the infrared, through the development of calibration standards and measurement protocols.
To achieve this, the successful candidate will receive training in the latest techniques in photoluminescence spectroscopy, spectral calibration and correction, and quantum yield theory and hardware. The candidate will routinely use state-of-the-art instrumentation, at the spectroscopy facilities at Heriot-Watt University and at Edinburgh Instruments Ltd, a world-leading company in the sector.
This project is in the field of photonics and optical instrumentation, a sector which employs over 80,000 people and it is the 5th most productive manufacturing sector in the UK.
Publications in high impact factor journals are expected as a result of the identification and assessment of calibration standards. This is an important milestone and would have large impact in the sector.
