title: A bis-cyclometalated iridium complex as a benchmark sensitizer for efficient visible-to-UV photon upconversion.
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.
