- Microshells: Photoresponsive Monodisperse Cholesteric Liquid Crystalline Microshells for Tunable Omnidirectional Lasing Enabled by a Visible Light-Driven Chiral Molecular Switch (Advanced Optical Materials 9/2014) (page 904)

A self-organized, phototunable 3D photonic superstructure is fabricated from a photoresponsive 1D liquid crystal using microfluidics. On page 845, Q. Li and co-workers show how the resulting monodisperse microshells are water-oil-water double emulsions, in which the oil phase consists of the photoresponsive liquid crystals. The cholesteric microshells exhibit band-edge lasing in all directions, and the wavelength of the resultant band-edge laser is tuned via the pumping laser, causing photoisomerization of the chiral molecular switch.

On page 855, J. C. Ho and co-workers exploit a simple photolithographic technique using surface-textured soft polymer films as optical masks for the area selective exposure of photoresists upon flood UV illumination. This allows rapid fabrication of periodic nanopatterns over large areas, and by simply varying the mask and tuning the exposure dose, patterns with different geometric characteristics can be obtained in a controllable manner. Importantly, these polymer masks can be used numerous times, making this technique a reliable low-cost alternative to the existing methods.
- Solar Cells: Synthesis of Organic–Inorganic Lead Halide Perovskite Nanoplatelets: Towards High-Performance Perovskite Solar Cells and Optoelectronic Devices (Advanced Optical Materials 9/2014) (page 837)

Highly crystalline organic-inorganic lead halide perovskite nanoplatelets are grown on muscovite mica by Q. H. Xiong and co-workers utilizing van der Waals epitaxial growth followed by thermally intercalating methyl ammonium halides. On page 838, the resultant CH3NH3PbI3 platelets show excellent optical properties with an electron diffusion length of more than 200 nm, which is approximately twice that of the solution-processed films, suggesting considerable promise for photovoltaics and opto-electronics.

The image shows an artist's abstraction of digitally controlled RYGB lasers color-mixed to create white light, created by Hanqing Kuang and George Wang. The long-term route to ultra-efficient and smart lighting might well be some variant of this architecture, as phosphors must give way to multi-color semiconductor electroluminescence. On page 809, the current status of solid-state lighting is reviewed by J. Y. Tsao et al., including some of the associated technological challenges.
