Long‐Term Study of Optical Nanoparticles Doped With Yb3+/Er3+ and Transition Metal Ions and their Real Application for Imaging and Temperature Sensing on Triticum Aestivum L.

Advanced Optical Materials, EarlyView.
This work shows a study on SrF2:Yb3+, Er3+ water colloid, additionally doped with transition metals (Sc3+ or Zn2+) to enhance observed emission, tested during 22 weeks of storage in ambient conditions. Due to high stability, excellent optical properties achieved under 975 nm excitation, and negligible phytotoxicity, the nanoparticles are applied for ...

Self‐Assembled Physical Unclonable Function Labels Based on Plasmonic Coupling

Advanced Optical Materials, EarlyView.
This article introduces advanced anti‐counterfeit labels crafted through DNA‐guided self‐assembly of plasmonic nanoparticles. Utilizing nanosphere lithography for dense and precise nanoparticle placement, these labels feature unique, unclonable optical signatures achieved through plasmonic coupling, detectable by an economical 3D‐printed dark field ...

Hyperphosphorescent OLEDs: Harnessing the Power of MR‐TADF Terminal Emitters

Advanced Optical Materials, EarlyView.
Hyperphosphorescent organic light‐emitting diodes (HP‐OLEDs) use phosphorescent sensitizers with multiresonant thermally activated delayed fluorescence terminal emitters. HP‐OLEDs show efficient, narrowband electroluminescence and moderate efficiency roll‐off.

Supramolecular Design of Polymeric Random Lasers

Advanced Optical Materials, EarlyView.
This research investigates the application of PolyHIPE scaffolds as scattering media inRLs. By modifying the scaffold's morphology, pore size, and surface chemistry, the dye distribution within the material is precisely controlled, achieving a tunable laser threshold.
