Drastic Mechanochromic Luminescence Through Fluorescence–Phosphorescence Switching in a Heavy‐Atom‐Free Organoboron Compound

open access: yesAdvanced Optical Materials, EarlyView.
A new heavy‐atom‐free, donor–acceptor‐type organoboron luminophore has been synthesized, which exhibits red room‐temperature phosphorescence (RTP) in the crystalline state. Furthermore, the amorphous solid generated by grinding shows green thermally activated delayed fluorescence (TADF), displaying distinct mechanochromic luminescence (MCL) through ...

Mechanoluminescence of Bi‐Activated NaYGeO4 Polycrystals and 3D Printed Scaffolds in the NUV/Blue and NIR Spectral Range

open access: yesAdvanced Optical Materials, EarlyView.
NUV/Blue and NIR emitting mechanoluminescent (ML) materials based on a Bi‐doped germanate compound (NYGOBx) are reported. 3D‐printing is used to fabricate complex scaffold devices from this material, suggested for use as mechanically‐activated light sources for functional illumination.

Carbonized Polymer Dots‐Based Spectrally Adaptable Photonic Microbarcodes

open access: yesAdvanced Optical Materials, EarlyView.
This study explores spectrally tunable photonics barcodes using carbonized polymer dots (CPDs) based on whispering gallery mode (WGM) photoluminescence. CPDs offer wavelength‐dependent emission from visible to near‐infrared (NIR), thereby enabling variable WGM emissions.

Coupled Optical Response of Armchair Graphene Nanoribbons and Single Wall Carbon Nanotube Hybrid Structures

open access: yesAdvanced Optical Materials, EarlyView.
A strong interaction between the five‐armchair graphene nanoribbons (GNRs) and the encapsulating single‐walled carbon nanotubes is identified. A reduction of the bandgap of the hybrid structure as well as additional proof for the single H‐terminations of the GNRs are confirmed through a combination of optical absorbance spectroscopy and density ...

Design Method of Time‐Multiplexed Ultrashort Throw Ratio Projection System with Low Distortion and Uniform Resolution

open access: yesAdvanced Photonics Research, EarlyView.
This work develops an ultrashort throw ratio (UTR) laser projection system using time‐multiplexed micro electro mechanical systems scanning. Trapezoidal distortion via vertical laser incidence control is eliminated and a systematic design method integrating a miniaturized catadioptric objective that maintains uniform optical étendue is proposed.

Exploring Gelatin‐A and Mouse Proline‐Rich Protein 5 as Probes for Wine Polyphenol Analysis by Quartz Crystal Microbalance with Dissipation Monitoring

open access: yesAdvanced Sensor Research, EarlyView.
This study presents a novel strategy for the detection of polyphenols in wine. By combining Quartz Crystal Microbalance with Dissipation Monitoring and original functionalization strategies, Gelatin A from porcine skin and Mouse Proline‐Rich Protein 5, polyphenols are successfully detected directly in wine without any prior sample preparation ...
