Wurst, Kai M. (author), Bender, Markus (author), Lauth, J.D. (author), Maiti, Sonam (author), Chassé, Thomas (author), Meixner, Alfred (author), Siebbeles, L.D.A. (author), Bunz, Uwe H.F. (author), Braun, Kai (author), Scheele, Marcus (author)An optical switch with two distinct resonances is formed by combining PbS nanocrystals and the conductive polymer poly[sodium 2-(2-ethynyl-4-methoxyphenoxy)acetate] (PAE) into a hybrid thin film. Infrared excitation of the nanocrystals invokes charge transfer and consecutive polaron formation in the PAE, which activates the switch for excited...journal article 2018

André, A. (author), Theurer, C. (author), Lauth, J.D. (author), Maiti, S. (author), Hodas, M. (author), Samadi Khoshkhoo, M. (author), Kinge, S. (author), Meixner, A. J. (author), Schreiber, F. (author), Siebbeles, L.D.A. (author), Braun, K. (author), Scheele, M. (author)We simultaneously surface-functionalize PbS nanocrystals with Cu 4,4′,4′′,4′′′-tetraaminophthalocyanine and assemble this hybrid material into macroscopic monolayers. Electron microscopy and X-ray scattering reveal a granular mesocrystalline structure with strong coherence between the atomic lattice and the superlattice of nanocrystals within...journal article 2017
