Bistable Photochromic Guest–Host Liquid Crystals for Rewritable and Switchable Photonic Devices

open access: yesAdvanced Functional Materials, EarlyView.
A photochromic DTCP‐based liquid crystal dye is incorporated into cholesteric liquid crystals (CLCs) to achieve optically and electrically tunable multistable states. In the open‐ring form, the system exhibits three electrically stable textures—planar, focal conic, and uniformly lying helix (ULH)—corresponding to reflective, scattering, and transparent

Quantifying Spin Defect Density in hBN via Raman and Photoluminescence Analysis

open access: yesAdvanced Functional Materials, EarlyView.
An all‐optical method is presented for quantifying the density of boron vacancy spin defects in hexagonal boron nitride (hBN). By correlating Raman and photoluminescence signals with irradiation fluence, defect‐induced Raman modes are identified and established an relationship linking optical signatures to absolute defect densities. This enables direct

Self‐Trapped Hole Migration and Defect‐Mediated Thermal Quenching of Luminescence in α‐ and β‐Ga2O3

open access: yesAdvanced Functional Materials, EarlyView.
Temperature‐dependent photoluminescence and first‐principles calculations reveal self‐trapped hole migration as the microscopic origin of thermal quenching in α‐ and β‐Ga2O3. The low migration barrier in α‐Ga2O3 enables defect trapping and enhances blue luminescence, while the higher barrier in β‐Ga2O3 preserves ultraviolet emission at elevated ...
