Congratulations to Georgie Burgoyne Morris, whose work on oxygen quenching of triplet-triplet annihilation upconversion (TTA-UC) in ureasil hosts was published in April in ACS Applied Optical Materials. 

This work, supported by Larissa Gomes Franca and former group member Abi Collins, explores how the structure of TTA-UC hosts impacts the ingress of oxygen, and how this interplays with the TTA-UC energy transfer processes to determine the overall performance. It hopes to set a precedent for the characterisation of oxygen permeability in TTA-UC hosts, and to inform the design of future host materials.
