Comparative Test of Novel Fluorescent Optical Antennas for LED‐ and Laser‐Based Optical Wireless Communications

Advanced Optical Materials, EarlyView.
New fluorescent optical antennas are realized and tested for diverse Optical Wireless Communication (OWC) applications. The fluorescent concentrator slabs, based on different organic fluorophores, convert and convey the digital data conveyed through intensity modulation of incoming light toward a small‐area photodiode.

Novel approach of SERS sensors AgNPs/PSi by incorporated MWCNT

Results in Chemistry
In this study, two types of nano photonics sensors silver nanoparticles/porous silicon (AgNPs/PSi) and silver nanoparticles/multi wall carbon nanotube/porous silicon (AgNPs/MWCNT/PSi) were formed and tested extensively. The porous silicon (PSi) substrate

Understanding the Optoelectronic Processes in Colloidal 2D Multi‐Layered MAPbBr3 Perovskite Nanosheets: Funneling, Recombination and Self‐Trapped Excitons

Advanced Optical Materials, EarlyView.
Mechanisms by which excitons and charge carriers can funnel and recombine in 2D multi‐layered MAPbBr3 Ruddlesden‐Popper perovskite nanosheets are missing. This femtosecond transient absorption spectroscopy study creates a comprehensive understanding of how directed transport, exciton‐exciton annihilation, and Auger recombination occur in colloidal ...

Plasmonic and Photonic Modes in Colloidal CuS Nanocrystals

Advanced Optical Materials, EarlyView.
Copper sulfide in the covellite phase (CuS) can exhibit exceptional optoelectronic properties with plasmonic and photonic absorption in its monolithic nanomaterial form. In this work, the phenomenon of near‐infrared (NIR) to visible electromagnetic field localization in ultrathin crystalline quasi‐2D CuS nanocrystals is demonstrated by mapping ...

Polarization‐Dependent Color Modulation in Electrodeposited Cellulose Nanocrystals and Birefringent Multilayers

Advanced Optical Materials, EarlyView.
This work demonstrates that wavelength selective reflection of circularly polarized light (CPL) of both handedness (right‐R or left‐L) can be achieved from self‐assembled cellulose nanocrystals (CNCs), breaking the inherent limitation of obtaining only L‐CPL reflection.
