An Examination of the Cs2NaInCl6 Luminescence: Interplay of Self‐Generated In+ and Doped Sb3+, Er3+/Yb3+ Ions

Advanced Optical Materials, EarlyView.
A new luminescence mechanism in Cs2NaInCl₆ is revealed through spontaneously formed In3+→In+ centers and Er3+/Yb3+/Sb3+ doping. Tunable visible, near‐infrared, downconversion, and upconversion emissions are demonstrated, while DFT calculations explain the electronic structure.

Controlling Polystyrene Particle Distribution in Colloidal Lithography For Correlated‐Disorder Structures

Advanced Optical Materials, EarlyView.
Colloidal lithography is a low‐cost, simple and scalable technique to fabricate correlated‐disorder nanostructures for light‐trapping in solar cells. This work investigates the control of polystyrene particle distribution in colloidal lithography, highlighting the importance of particle surface functionalization as well as the ability to tune the ...

Hybridization of Gap Plasmons and Grating‐Coupled Surface Plasmon Polaritons in Metal Nanoparticle Cluster Arrays on a Mirror

Advanced Optical Materials, EarlyView.
Here we use a template‐assisted self‐assembly approach of metal colloids onto metal films to produce hybrid plasmonic metasurfaces that integrate nanoparticle‐on‐mirror cavities with periodic metal colloid arrays. The resulting coupling between gap plasmons and grating‐coupled surface plasmon polaritons enables programmable hybrid modes with tailored ...

Inverse‐Designed Superchiral Hot Spot in Dielectric Meta‐Cavity Toward Ultra‐Compact Enantioselective Detection

Advanced Optical Materials, EarlyView.
Linearly polarized incident light with normal incidence creates enhanced optical chirality hotspots on the metasurface. Several orders of magnitude optical chirality enhancement offers a promising route toward highly sensitive, compact chiral spectroscopy.

Information Transmission Strategies for Self‐Organized Robotic Aggregation

Advanced Robotics Research, EarlyView.
In this review, we discuss how information transmission influences the neighbor‐based self‐organized aggregation of swarm robots. We focus specifically on local interactions regarding information transfer and categorize previous studies based on the functions of the information exchanged.
