- Stimulus-Responsive Thin-Film Photonic Crystals from Rapid Self-Assembly of Block Copolymers for Photopatterning
Yeo-Wan Chiang, Jhih-Jyun Chang, Chung-Yi Chou, Cheng-Sian Wu, En-Li Lin and Edwin L. Thomas
Article first published online: 3 JUL 2015 | DOI: 10.1002/adom.201500177
Rapid self-assembly (≈15 min) of parallel-aligned lamella-forming block-copolymer photonic-crystal thin films is carried out through the manipulation of solvent evaporation. A well-defined photopatterned thin-film photonic crystal can exhibit either a lower redshift reflectivity or unresponsiveness toward the external stimulus by control of its exposure time to UV irradiation.

The manipulation of terahertz (THz) waves is implemented by 1-bit THz coding metamaterials. The reflection and scattering wave can be controlled by varying the coding sequence. Using this methodology, a wideband and polarization-independent THz thin-film metamaterial with extremely low specular reflection and scattering waves is demonstrated successfully. This metamaterial is also flexible and conformal to the curved surface, which offers widespread applications.
- The Tunable White-Light and Multicolor Emission in An Electrodeposited Thin Film of Mixed Lanthanide Coordination Polymers
Huiping Liu, Tianshu Chu, Zilong Rao, Shuoyu Wang, Yangyi Yang and Wing-Tak Wong
Article first published online: 30 JUN 2015 | DOI: 10.1002/adom.201500203
A white-light-emitting lanthanide coordination polymer thin film is fabricated for the first time by electrodeposition based on a novel hexanuclear lanthanide cluster, in which, Tb3+ generates green emission and enhances the Eu3+-centered red emission through energy transfer process; the ligand generates blue emission. Notably, white-light emission with CIE coordinates of (0.33, 0.34) is obtained by balancing Tb3+/Eu3+ ratio and excitation wavelength.
- Gate Tuning of High-Performance InSe-Based Photodetectors Using Graphene Electrodes
Wengang Luo, Yufei Cao, Pingan Hu, Kaiming Cai, Qi Feng, Faguang Yan, Tengfei Yan, Xinhui Zhang and Kaiyou Wang
Article first published online: 29 JUN 2015 | DOI: 10.1002/adom.201500190
By using graphene as the transparent electrodes to modify the difference of the work function between the electrodes and the InSe, the response time of an InSe-based photodetector can be down to 120 μs. It can also be tuned by the back-gate voltage from 310 μs down to 100 μs. Simultaneously, the photoresponsivity can reach as high as 60 A W−1.
- Anisotropic Light Transport in White Beetle Scales

The extremely brilliant whiteness shown by the Cyphochilus beetle is generated by multiple scattering of light inside the ultrathin scales that cover its body, whose interior is characterized by an anisotropic nanostructured network of chitin filaments. It is demonstrated that the structural anisotropy of the network is crucial in order to achieve high broadband reflectance from such a thin, low-refractive-index system.
