Wireless Nano Irradiance Meter Based on Upconversion Luminescence Lifetime

open access: yesAdvanced Optical Materials, EarlyView.
A wireless nano irradiance meter is developed based on upconversion nanoparticles that enabled local readouts through their luminescence lifetime. This method allows for remote and precise light irradiance quantification in complex media, offering significant potential for light‐based technologies such as photodynamic therapy and nanothermometry ...

The Impact of Donor‐Orientation on the Emission Properties of Chlorinated Trityl Radicals

open access: yesAdvanced Optical Materials, EarlyView.
Chlorinated trityl radicals with electron‐donating groups enable efficient red emission for optoelectronics. Donor orientation and steric constraints regulate vibronic coupling, influencing luminescence. A novel trityl derivative with restricted donor alignment minimizes non‐radiative decay, enhancing quantum yield.

Nd(III)‐Based Temperature‐Independent Manometer and Pressure‐Independent Thermometer with Slow Relaxation of Magnetization

open access: yesAdvanced Optical Materials, EarlyView.
The Neodymium(III) macrocyclic complex [NdL(CF3SO3)3] serves as a non‐contact, bifunctional sensor for temperature and pressure, displaying field‐induced Single Molecule Magnet (SMM) behavior. At 3 GPa, triflate rotations halt, triggering a disorder‐order phase transition from centrosymmetric phase α to noncentrosymmetric high‐pressure phase β.

Dynamic Structural Colors in Cholesteric Cellulose Composites: Achieving Spatial and Temporal Control

open access: yesAdvanced Optical Materials, EarlyView.
By combining static and time‐resolved optical, structural, and rheological techniques, we demonstrate that the blue‐shift upon solidification of ethyl cellulose‐acrylic acid mesophases corresponds to the reorientation of cholesteric domains. Modulating the mesophase chain mobility and photopolymerization reaction kinetics enables solid chiral nematic ...
