- Biomimetic Chiral Nematic Mesoporous Materials from Crab Cuticles
Thanh-Dinh Nguyen and Mark J. MacLachlan

Photonic chitin membranes with the Bouligand structure are created from king crab endocuticles. Within the cuticle membranes, chitin nanofibrils are organized into a left-handed chiral nematic structure to evolve colorful, circularly polarized iridescence. The photonic porous chitin is used as a platform to make mesoporous silica and nitrogen-doped carbon replicas that mimic the twisted chitin nanofibril membranes.

Solvated microcrystals of C60 and C70 prepared by co-solvent precipitation with methylbenzenes and 2-propanol as good and poor solvents, respectively, display enhanced photoluminescence over pristine fullerenes. Monodisperse nonspherical colloids with diverse morphology including hexagonal platelets and rods with facets, hollow ends, or ‘flower-like’ cross-sections, are grown based on the concentration and injection volume of the fullerene solution.

Room temperature electroluminescence from van der Waals layered semiconductor junctions is demonstrated. The junctions are fabricated by exfoliation and direct mechanical adhesion. These heterostructures are based on direct-bandgap III–VI layered crystals and have atomically flat interfaces, a well-defined band lineup, and a broad optical response from the near-infrared to the visible spectral range
- Highly Efficient Light-Emitting Diode of Graphene Quantum Dots Fabricated from Graphite Intercalation Compounds
Sung Ho Song, Min-Ho Jang, Jin Chung, Sung Hawn Jin, Bo Hyun Kim, Seung-Hyun Hur, Seunghyup Yoo, Yong-Hoon Cho and Seokwoo Jeon

Graphene quantum dot (GQD) light-emitting diodes (GQD-LEDs) are shown to have an electroluminescence exceeding 1000 cd m-2. These devices are possible due to a novel synthesis method to create GQDs with minimal oxidation, guaranteeing high quantum yields via the solvothermal formation of graphite intercalation compounds between graphite powder and sodium potassium tartrate. The GQDs are incorporated into polymeric host layers in a multilayer device and irradiate blue (~400 nm) emission.
- Free-Standing, Single-Crystalline Parallelogram Sb Shallow-Doped ZnO Wave-Guided Optical Resonators
Yang Liu, Hongxing Dong, Jian Lu, Jingxin Zhan, Jingzhou Li, Zhanghai Chen and Long Zhang
Article first published online: 19 AUG 2014 | DOI: 10.1002/adom.201400269
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.
