- Post-treatment-Free Solution-Processed Non-stoichiometric NiOx Nanoparticles for Efficient Hole-Transport Layers of Organic Optoelectronic Devices
Fei Jiang, Wallace C. H. Choy, Xinchen Li, Di Zhang and Jiaqi Cheng
Article first published online: 26 MAR 2015 | DOI: 10.1002/adma.201405391
High-quality non-stoichiometric NiOx nanoparticles are synthesized by a facile chemical precipitation method. The NiOx film can function as an effective hole-transport layer (HTL) without any post-treatments, while offering wide temperature applicability from room temperature to 150 °C. A high efficiency of 9.16% is achieved in organic solar cells using the NiOx HTL. A better performance in a NiOx-based organic light-emitting diode is observed, compared with a device using PEDOT:PSS.

Lead-free bismuth-based perovskite oxides with polarization directed along the p primitive perovskite unit cell edge, analogous to tetragonal PbTiO3, are synthesized at ambient pressure. Enhanced piezoelectric properties, large polarizations, and high depolarization temperatures are observed in the wide morphotropic phase boundary region formed with a rhombohedral phase, with up to 92.5% Bi on the perovskite A site.
- A Lightweight TiO2/Graphene Interlayer, Applied as a Highly Effective Polysulfide Absorbent for Fast, Long-Life Lithium–Sulfur Batteries

An integrated, selective interlayer structure is developed to further mitigate the diffusion of polysulfides, simply by coating the surface of a C–S cathode with a graphene/TiO2 film. It is found that the application of the graphene/TiO2 film as an interlayer enables the porous carbon nanotubes–S cathode to exhibit a high reversible specific capacity and extraordinarily excellent cycling stability.
- Rationally Designed Energy Transfer in Upconverting Nanoparticles
Emory M. Chan, Elizabeth S. Levy and Bruce E. Cohen
Article first published online: 24 MAR 2015 | DOI: 10.1002/adma.201500248
Significant advances in the analysis and theoretical modeling of upconverting nanoparticles are beginning to reveal the complex details of their energy transfer pathways. This article reviews recent work on the development of complex architectures that facilitate the rational design and precise engineering of optical processes in upconverting nanoparticles.
- Stable and Low-Threshold Optical Gain in CdSe/CdS Quantum Dots: An All-Colloidal Frequency Up-Converted Laser
Burak Guzelturk, Yusuf Kelestemur, Kivanc Gungor, Aydan Yeltik, Mehmet Zafer Akgul, Yue Wang, Rui Chen, Cuong Dang, Handong Sun and Hilmi Volkan Demir
Article first published online: 24 MAR 2015 | DOI: 10.1002/adma.201500418
An all-solution processed and all-colloidal laser is demonstrated using tailored CdSe/CdS core/shell quantum dots, which exhibit highly stable and low-threshold optical gain owing to substantially suppressed non-radiative Auger recombination.
