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

Advanced 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 ...

Toward Enhancing Chiro‐Optical and Magneto‐Optical Properties of Magnetic Nanocrystals by Surface Plasmons

Advanced Optical Materials, EarlyView.
Here, recent progress is highlighted in colloidal magnetoplasmonic hybrid nanomaterials, with a focus on chiral plasmonics. Metal nanocrystals with intrinsic chiroptical features can lead to a combination of chiral plasmonics and magneto‐optics effects when interacting with the magnetic counterpart, offering a foundation for systematically designing ...

Bright LaF3:Eu@Ir Phosphors Combining Two‐Photon Excitation, d → f Energy Transfer and Tunable Time‐Gated Chromaticity for Multicolor Cell Imaging

Advanced Optical Materials, EarlyView.
The surface functionalization of Eu‐doped LaF3 particles with a two‐photon absorbing IrIII complex results in the formation of ultrabright Eu:LaF3 phosphors, which exhibit a combination of short‐lived IrIII and long‐lived EuIII‐sensitized emissions. These Ir/Eu hybrids are effectively internalized by HEK‐293 cells without causing toxic effects, thereby

Ellipticity‐Controlled Exceptional Points and Cross‐Polarized Phase Singularities in Multi‐Layer Silicon Guided Mode Resonant Metasurfaces

Advanced Optical Materials, EarlyView.
Omni‐polarizers that pull all input polarization states to an elliptical or linear polarization can be made using highly resonant bi‐layer metasurfaces. The ellipticity of the selected polarization can be controlled by choosing the layer separation.

Tunable‐Wavelength Broadband Liquid‐State Carbon‐Quantum‐Dot Lasers

Advanced Optical Materials, EarlyView.
This work provides a gain‐induced waveguide structure to achieve programmable mode spacing by coupling liquid‐state lasing of carbon quantum dots to a vertically placed aluminum mirror, enabling an unprecedented transition from random lasing to multimode lasing without cumbersome micromanufacturing, even single‐mode lasing at a wide range from 641 to ...
