- Free-Standing, Single-Crystalline Parallelogram Sb Shallow-Doped ZnO Wave-Guided Optical Resonators

Sb shallow-doped ZnO microwire wave-guided microcavities are synthesized. The photoluminescence properties and UV lasing of such ZnO microcavities with Sb elements annealed in different atmospheres are investigated through low-temperature spectrum detection technology. The ZnO microcavities provide a promising test-bed for investigating new optical modulation behaviour, cavity physics, and for novel photoelectronic devices.

A new approach to light-induced tuning of extraction and injection barrier heights as well as the series resistance is realized by introducing TiO2 nanocrystals as the electron-extraction layer of organic photodetectors. TiO2-based UV photodetectors at the photovoltaic mode achieve a ultrahigh on/off ratio of 105, which is the best value for UV organic photodetectors.

Exciton–polaritons are quasi-particles with the capability to undergo phase transition into a coherent hybrid state of light and matter. Polaritons in organic microcavities have attracted increasing attention for their characteristic of reaching condensation at room temperature. The new relaxation channels observed under the strong coupling regime could allow a significant enhancement of the photoluminescence intensity as compared to the bare dye.
- Highly Efficient and Stable Phosphorescent Organic Light-Emitting Diodes Utilizing Reverse Intersystem Crossing of the Host Material

An efficient and stable green phosphorescent light-emitting diode (PHOLED) is demonstrated by employing a suitable host. The transient photoluminescence characteristics show that the triplet excitons of the host are rapidly transferred to the dopant and emit phosphorescence in the stable PHOLED. Most of the triplet excitons of the host are transferred to the dopant within 10 ns following the Förster process via a singlet excited state of the host.
- Large-Area Antenna-Assisted SEIRA Substrates by Laser Interference Lithography
Shahin Bagheri, Harald Giessen and Frank Neubrech
Article first published online: 31 JUL 2014 | DOI: 10.1002/adom.201400218
Laser interference lithography is utilized to fabricate large-area plasmonic antenna substrates with tunable plasmonic resonances in the near- and mid-infrared spectral range for surface-enhanced infrared absorption (SEIRA). The broad applicability of such SEIRA substrates is demonstrated by enhancing the infrared vibrational signals of a monolayer octadecanethiol and by monitoring the ultraviolet degradation of a polymer via the decrease of its specific vibrational modes.
