A paper recently published in Chemistry: A European Journal (Wiley Online Library/ChemPubSoc Europe) by first author and KESS 2 student Kaitlin Phillips, of Prof. Simon Pope’s research group in Cardiff University (June 2018), together with collaborators in China, has shown that new organometallic species can be developed that show remarkable electronic properties.
KESS 2 project researchers, working in collaboration with STG Aerospace and supported by European Social Funds through the Welsh Government, report the development of new luminescent materials that demonstrate highly efficient light upconversion. Upconversion is the process by which low energy light is converted into high energy light, and has wide ranging applicability to the development of light emitting materials, photovoltaics and photocatalysis.
The authors describe how this new class of material has now set a new world-leading benchmark in the reported efficiency of light upconversion.
Prof. Simon Pope said “The focus of this project is the design, development, characterisation and application of new luminescent materials for potential application in the aerospace industry. The work describes red light emitting materials that also demonstrate highly efficient light upconversion. Our aim is to explore the applicability of these materials in the development of light emitting devices that address the industry need for efficient lighting displays and surface coatings”.
