Zone‐Sectored Organic Crystals with Spatially Resolved Exciton Dynamics
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.

Quasi‐bound states in the continuum on the Bloch surface wave platform are demonstrated, exhibiting high Q‐factors due to strongly suppressed radiative losses and high sensitivity arising from the large evanescent field inherent to the surface wave. The resonance shows clear shifts after each surface molecular functionalization step, highlighting its ...
