Journal ArticleDOI
Luminescence properties of PPV-based copolymers with crown ether substituents
Jorge Morgado,Franco Cacialli,Richard H. Friend,Beng Sim Chuah,Stephen C. Moratti,Andrew B. Holmes +5 more
TL;DR: In this article, the optical properties of four poly(p-phenylenevinylene) (PPV)-based statistical copolymers, which combine monomers of highly luminescent polymers and monomers carrying crown ether side groups, were presented.
Journal ArticleDOI
Black GaAs by Metal-Assisted Chemical Etching.
TL;DR: The anisotropic metal-assisted chemical etching of GaAs wafers exploiting the lower etching rate of the monoatomic Ga<111> and <311> planes is demonstrated and it is shown that the reflectance of the roughened surface of black GaAs reduces up to ∼50 times compared to polished wafer, nearly doubling its absorption.
Journal ArticleDOI
Virtually pure near-infrared electroluminescence from exciplexes at polyfluorene/hexaazatrinaphthylene interfaces
Giulia Tregnago,Charlotte Fléchon,Sunil Choudhary,Cristian Gozalvez,Aurelio Mateo-Alonso,Franco Cacialli +5 more
TL;DR: In this article, the formation of an exciplex state at the heterojunction of an electron-transporting material, a functionalized hexaazatrinaphthylene, and a hole-transport material, poly(9,9-dioctylfluorene-alt-N-(4-butylphenyl)diphenylamine) (TFB) was reported.
Journal ArticleDOI
Low-frequency resistance fluctuation measurements on conducting polymer thin-film resistors
TL;DR: In this article, low-frequency resistance fluctuations were measured on polypyrrole thin-film resistors and the dependence of the noise magnitude on the applied dc voltage was studied revealing that the noise cannot be ascribed only to equilibrium resistance fluctuations.
Journal ArticleDOI
Dopant optimization for triplet harvesting in polymer photovoltaics
TL;DR: In this article, the authors investigated the dependence of the characteristics of polymer photovoltaic cells on the concentration of doping of the active layers by heavy-metal complexes, and found that there is an optimum doping load above which the device performance severely deteriorates.
