Blue organic long-persistent luminescence via upconversion from charge-transfer to locally excited singlet state

Abstract Long-persistent luminescence (LPL) materials have applications from safety signage to bioimaging; however, existing organic LPL (OLPL) systems do not align with human scotopic vision, which is sensitive to blue light. We present a strategy to blueshift the emissions in binary OLPL systems b...
