Laser‐Written Ruby Emitters in MXenes: Transforming Residual Impurities Into Integrated Narrowband Luminescent Probes

open access: yesAdvanced Optical Materials, EarlyView.
Laser writing converts residual aluminum in MXenes into bright ruby emitters with laser‐like photoluminescence. This approach provides a universal optical tool for mapping material purity. Luminescence sensitivity to temperature, pressure and chemical environment turns synthesis liabilities into assets, enabling the formation of built‐in optical probes

Multi‐Channel Quantum Dot Single‐Photon Sources on a Fiber‐Integrated Platform

open access: yesAdvanced Optical Materials, EarlyView.
A breakthrough in achieving a multiple, tunable array of quantum photonic devices is presented. By combining an optimal nanophotonic cavity, individual device transfer process, and integrated electrodes on a V‐groove fiber, the all‐fiber integrated system exhibits capabilities of low‐temperature cooling, efficient single‐photon transmission, selective ...

Directionally Asymmetric Holographic Imaging for Arbitrary Polarization States Using Janus Metasurfaces

open access: yesAdvanced Optical Materials, EarlyView.
We demonstrate single‐layer titanium dioxide Janus metasurface holograms that achieve directionally asymmetric imaging under forward and backward illumination. By integrating the Dammann grating principle with precise phase control, our design produces high‐fidelity holographic images for arbitrary polarization states at 532 nm, simplifying fabrication,

Resolving Dye Embedment in MOF‐5: Multimodal Evidence for Perylene‐Based Guest Encapsulation

open access: yesAdvanced Optical Materials, EarlyView.
Unambiguous discrimination between surface‐adsorbed and pore‐incorporated photoactive dyes remains a key challenge in hybrid MOF systems. This study presents a comprehensive multi‐technique approach ‐ combining PXRD, IR spectroscopy, N2 physisorption, and time‐resolved photoluminescence ‐ complemented by DFTB3 molecular dynamics, to elucidate the ...
