Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics
Advanced Materials, EarlyView.The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

Advanced Materials, EarlyView.This paper describes room‐temperature polariton lasing with high circular polarization from deformed plasmonic Kagome lattice cavities strongly coupled to colloidal CdSe nanoplatelets. Spin‐selectivity from cavity modes resulted in control over the handedness of circular polarization as well as the direction of polariton lasing, opening prospects for ...

Dynamic Optical Lattices Through Conducting Polymer‐Gated Confinement
Advanced Materials, EarlyView.The conducting polymer gate is incorporated into organic dielectric lattices to control the dynamic switching of nonlocal Mie resonances in the visible/NIR regions. The “closed gate” from oxidized PEDOT confines the light within dielectric nanocylinders and activates nonlocal Mie resonances, while the “opened gate” from reduced PEDOT facilitates ...

Photonic Crystal Enhanced Microscopy on a 2D Photonic Crystal Surface
Advanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.This work demonstrates the design, fabrication, and the first‐time test of a 2D photonic crystal surface for photonic resonator absorption microscopy. The designed surface uniformly enhances electromagnetic near fields, achieving > 100% improved detecting uniformity for surface‐captured AuNPs from a blocking biosensor assay aimed for detecting SARS‐CoV‐
