Zone‐Sectored Organic Crystals with Spatially Resolved Exciton Dynamics
Advanced Optical Materials, Volume 14, Issue 5, 2 February 2026.Novel type of rubrene microcrystals in the orthorhombic phase are grown exhibiting spatial contrast in spectra and dynamics due to differences in unit cell orientation. Distinct zones selectively host redshifted luminescence band at ≈650 nm driven by high photon absorption.

Advanced Optical Materials, Volume 14, Issue 6, 9 February 2026.A proof‐of‐concept of a thermally‐tunable cathodoluminescence‐based light source is demonstrated using a wide‐bandgap z‐cut ZnO crystal as anode, resulting in the ultraviolet (UV) emission peak shifting from 398 nm to ~409 nm (3.115‐3.032 eV). Our results establish the feasibility of a compact, field‐deployable UV source with potential for gas sensing ...
