Abstract

To resolve the biggest problem in visible-to-UV photon upconversion based on sensitized triplet–triplet annihilation—the quenching of upconverted fluorescence by sensitizers—we discovered a superior sensitizer with less UV absorption intensity that enables highly efficient, low-power (0.78 mW cm⁻²) visible-to-UV upconversion.
