Frontiers of Photon Upconversion Based on Triplet-triplet Annihilation (#420)
First demonstrated decades ago, photon upconversion based on triplet-triplet annihilation (TTA) has drawn increasing attention lately, largely because it can potentially utilize low power density, non-coherent light source. The possibility to achieve efficient upconversion from non-coherent light source has great implication to solar harvesting, as sub-bandgap photons in the solar spectrum can then be utilized. There has been tremendous progress in this field recently, as indicated by the rapidly increasing number of publications related to this subject. While most of the fundamental understandings of TTA upconversion have been established by now, there is plenty of room for further research efforts toward the translational aspect of the subject. This symposium covers all aspects of TTA upconversion, including the design, synthesis and characterization of molecules involved, device design and development, theoretical consideration, and new observations pertinent to the TTA process. This symposium aims to bring together diverse researchers with cutting-edge topics, progress, and new directions of the field, stimulate idea exchanges among participants, and catalyze collaborations for further development of TTA upconversion into applications.
