    • The present invention generally relates to composition and methods for upconverting light. In some embodiments, the composition and methods comprise an organic material, a nanocrystal, and a ligand capable of facilitating energy transfer between the nanocrystal and the organic material. In certain embodiments, the nanocrystal has a first excited energy state with an energy greater than a triplet state of the organic material. The organic material, in some embodiments, may be aromatic and/or include one or more pi-conjugated carbon-carbon double bonds. In some cases, incident light may be absorbed by the nanocrystal to produce triplet excitons. The triplet excitons may then transfer from the nanocrystal to the organic material and undergo triplet-triplet annihilation, creating a singlet state of approximately twice the energy of the triplet exciton. In certain embodiments, the singlet state fluoresces, resulting in the formation of a high energy photon.
    • 本发明一般涉及用于上变频光的组合物和方法。 在一些实施方案中,组合物和方法包括能够促进纳米晶体和有机材料之间的能量转移的有机材料,纳米晶体和配体。 在某些实施方案中,纳米晶体具有能量大于有机材料的三线态的第一激发能态。 在一些实施方案中,有机材料可以是芳族的和/或包括一个或多个π-共轭碳 - 碳双键。 在一些情况下,入射光可以被纳米晶体吸收以产生三线态激子。 然后,三线态激子可以从纳米晶体转移到有机材料并经历三重态三重态湮灭,形成三线态激子的能量的大约两倍的单线态。 在某些实施方案中,单线态发荧光,导致形成高能光子。
