Highly luminescent π-conjugated polymeric microspheres were fabricated through self-assembly of energy-donating and energy-accepting polymers and their blends. To avoid macroscopic phase separation, the nucleation time and growth rate of each polyme

Enwrapping Conjugated Polymer Microspheres with Graphene Oxide Nanosheets

Autor: Yohei Yamamoto, Junji Nakamura, Axel Lorke, Takahiro Kondo, Soh Kushida, Junpei Kuwabara, Takaki Kanbara, Daniel Braam, Yusuke Aikyo

Publikováno v: Chemistry Letters. 45:1024-1026

Water-dispersible conjugated polymer microspheres were obtained by enwrapping with graphene oxide (GO) nanosheets. Simply mixing the polymer microspheres and GO in water results in an exclusive formation of GO-wrapped microspheres. The photoluminesce

GaSb quantum dots on GaAs with high localization energy of 710 meV and an emission wavelength of 1.3 µm

Autor: Daniel Braam, Dieter Bimberg, Axel Lorke, Johannes M. Richter, T. Nowozin, Johannes Strassner, Thomas Henning Loeber, Leo Bonato, Henning Fouckhardt

Publikováno v: Journal of Crystal Growth. 404:48-53

We report on the epitaxial growth of GaSb quantum dots (QDs) that show photoluminescence at a wavelength of around 1.3 µm and a high hole localization energy of up to 710 meV with a capture cross-section of 1×10 −13 cm 2 . The QDs were grown in S

Optically induced mode splitting in self-assembled, high quality-factor conjugated polymer microcavities

Autor: Takaki Kanbara, Yohei Yamamoto, Soh Kushida, Hitoshi Saito, Axel Lorke, Junpei Kuwabara, Günther M. Prinz, Robert Niemöller, Daniel Braam

Publikováno v: Scientific Reports

We investigate the whispering gallery modes (WGMs) of self-assembled single microspheres. They consist of a recently developed highly fluorescent π-conjugated copolymer and exhibit excellent optical properties with Q-factors up to 104. Under continu

Electron-beam induced nano-etching of suspended graphene

Autor: A. Ganczarczyk, Martin Geller, Axel Lorke, Jens Sonntag, Günther M. Prinz, Benedikt Sommer, Daniel Braam

Publikováno v: Scientific Reports

Besides its interesting physical properties, graphene as a two-dimensional lattice of carbon atoms promises to realize devices with exceptional electronic properties, where freely suspended graphene without contact to any substrate is the ultimate, t

Whispering gallery resonance from self-assembled microspheres of highly fluorescent isolated conjugated polymers

Autor: Chengjun Pan, Soh Kushida, Axel Lorke, Kazunori Sugiyasu, Thang Duy Dao, Masayuki Takeuchi, Yohei Yamamoto, Daniel Braam, Kenichi Tabata, Satoshi Ishii, Tadaaki Nagao

Self-assembly of highly fluorescent isolated conjugated polymers (ICPs), comprising alternating phenylene moieties with an insulating cyclic side chain and different arylene moieties, was comprehensively studied. Two out of nine ICPs were identified

Whispering gallery mode photoemission from self-assembled poly-para-phenylenevinylene microspheres

Autor: Yohei Yamamoto, Soh Kushida, Axel Lorke, Daniel Braam

Poly[2-methoxy-5-(3,7-dimethyloctyloxy)-1,4-phenylenevinylene] (MDMOPPV) self-assembles to form well-defined spheres with several micrometers in diameter upon addition of a methanol vapor into a chloroform solution of MDMOPPV. The single sphere of MD
