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

open access: yesAdvanced 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 ...

Tunneling in Persistent Luminescence

open access: yesAdvanced Optical Materials, EarlyView.
Key experimental criteria are provided for the occurrence of thermal/athermal tunneling and localized transitions. Many experimental studies of PersL have assigned tunneling on the basis of the linear relationship of PersL decay between intensity, I, and time, t−k, where k is a constant or I−1 versus t.

High‐Efficiency Blue‐Emitting Multi‐Resonance TADF Organic Light‐Emitting Diodes Constructed on Spiro Quinolinoacridine/Fluorene‐diphenylphosphine Oxide Positional Isomers

open access: yesAdvanced Optical Materials, EarlyView.
We report spiro‐configured hosts constructed on the assembly of a quinolinoacrdine unit and different fluorene positional isomers for high‐performance blue MR‐TADF Organic Light‐Emitting Diodess. The v‐DABNA:CN‐Ir emissive layer combination with SQA‐4‐FPOPh2 as host shows a narrowband emission peak and a high maximum external quantum efficiency of 22.9%

Thermo‐Optical Analysis of Surface‐ and Volume‐Additivated Polymer Powders for Near‐Infrared Laser Powder Bed Fusion

open access: yesAdvanced Photonics Research, EarlyView.
Precipitated PA11 powders for laser powder bed fusion are additivated with small amounts of carbon black nanoparticles on and in the particles. The position of the nanoparticles has a strong impact on dispersion, crystallization, and thermal oxidation.
