Green color-conversion media (CCM) with enhanced photoluminescence and stability are developed using a perylene-based host and t-butyl modified DMQAs as the dopant. The resulting CCM films exhibited PLQY of 58% and near twice longer lifetime than the unsubstituted DMQA, while maintaining high blue light absorption of 99% with a 500 nm thickness.
