A study was conducted to demonstrate the infrared (IR) limit of the triplet-triplet annihilation (TTA)-supported up-conversion (UC) of tetraanthraporphyrin. The fundamental advantage of the TTA-supported UC is its independence on the coherence of the excitation light. It was demonstrated that the TTA-supported UC approach also resolves another demanding limitation of the conventional methods for UC. Another significant advantage of the new approach, was the low intensity needed to achieve high quantum yields on the order of 2-4% in inorganic solutions. The combination of these characteristics and possibilities make energetically conjoined TTA-UC suitable for diverse applications, such as all-organic, flexible, transparent displays, and up-converter devices.
