Journal ArticleDOI
Photon upconversion based on sensitized triplet-triplet annihilation
TL;DR: In this paper, the authors reviewed all the operational examples reported to date, and measurement techniques applied to these low-power nonlinear processes, in many instances, direct visualization of this phenomenon is presented in solution and within various polymeric host materials.
Journal ArticleDOI
Boron dipyrromethene chromophores: next generation triplet acceptors/annihilators for low power upconversion schemes.
TL;DR: The current systems represent the first examples of photon upconversion where aromatic hydrocarbons do not serve the role of triplet acceptor/annihilator and the nature of the current chromophore compositions permitted highly reproducible upconverted quantum efficiency determinations while permitting the evaluation of the triplet-triplet annihilation quantum yields in both instances.
Journal ArticleDOI
Triplet Sensitized Red-to-Blue Photon Upconversion
TL;DR: In this article, perylene was used as the triplet sensitizer and perylene as the energy acceptor/annihilator in deaerated benzene to achieve red-to-blue upconversion with a record 0.8 eV anti-Stokes shift.
Journal ArticleDOI
Influence of Temperature on Low-Power Upconversion in Rubbery Polymer Blends
TL;DR: The upconverting properties of a dye cocktail composed of palladium(II) octaethylporphyrin and 9,10-diphenylanthracene and DPA were investigated and the phosphorescence intensity decay of PdOEP in the polymer host, Tecoflex EG-80A, adequately fits to a sum of two exponential functions as well as the Kohlrausch-Williams-Watts (KWW) stretched exponential model.
Journal ArticleDOI
Pd(II) phthalocyanine-sensitized triplet-triplet annihilation from rubrene.
TL;DR: The current study represents the first example of photon upconversion using a phthalocyanine triplet sensitizer, furthering the notion that anti-Stokes light-producing sensitized TTA appears to be a general phenomenon as long as proper energy criteria are met.
