Cr3+‐Doped γ‐ and β‐Gallium Oxide Nanoprobes for Bioimaging: Synthesis, Persistent Luminescence, and Biocompatibility

open access: yesAdvanced Optical Materials, EarlyView.
γ‐Ga2O3:Cr3+ nanospheres are synthesized and transformed into colloidal β‐Ga2O3:Cr3+ nanoparticles (NPs) enabling to establish the relationships between their crystal structures and their NIR photoluminescence and persistent luminescence (PersL). Cytotoxicity and in vivo toxicity studies indicate that β‐Ga2O3:Cr3+ NPs are adequate nanoprobes for ...

Intracellular Monitoring of Luminescent Ag2S Nanoparticles in Fibroblasts

open access: yesAdvanced Optical Materials, EarlyView.
This study investigates the long‐term luminescence behavior of Ag2S quantum dots (AS QDs) with three surface ligands (DTDTPA, 11MUA, PEG) in fibroblasts over 9 days. AS‐PEG showed stable uptake and enhanced NIR‐II emission, while others decreased due to oxidative stress.

Illuminating Advances in Materials: Optical Physical Unclonable Functions for Security Applications

open access: yesAdvanced Optical Materials, EarlyView.
This review highlights Optical Physical Unclonable Functions (OPUFs) as secure, light‐driven authentication tools. It surveys material platforms including optical fibers, low‐dimensional materials, luminophores, plasmonic nanoparticles and rare earth OPUFs systems.

Evolution of Collective, Radiative Plasmon Coupling in Confined, Soft Colloidal Films

open access: yesAdvanced Optical Materials, EarlyView.
Plasmon resonance coupling is continuously monitored during the uniaxial manipulation of a 2‐dimensional soft colloidal film containing hexagonally arranged spherical gold nanocrystals. This is realized by the in situ spectroscopic investigation of a monolayer of plasmonic core‐shell microgels confined at the air/water interface that is compressed in a
