Polymer Dots Exhibiting Multi‐Resonant Thermally Activated Delayed Fluorescence for Cellular Imaging

open access: yesAdvanced Optical Materials, EarlyView.
By copolymerizing with a host material, a multiple resonance thermally activated delayed fluorescent (MR‐TADF) emitter quinolino[3,2,1‐de]acridine‐5,9‐dione (QAO) is successfully assembled into water‐dispersible polymer dots (Pdots). Photophysical measurements and multichannel fluorescence imaging studies show that the narrowband emission from the MR ...

High Contrast and High Efficiency Optical Weighting for Integrated Photonic Computing

open access: yesAdvanced Optical Materials, EarlyView.
Herein, a combined pulse optical weighting scheme is proposed for photonic synapses. Employing a 4 μm$\umu{\rm m}$ long non‐volatile phase‐change material covered on a straight waveguide, a transmission contrast of 31.2 dB is achieved. By exploiting the non‐Arrhenius behavior of the material, the crystallization energy is reduced to 107 pJ, with ...

TADF Host Engineering for Improved Pure Blue Matrix‐Free Hyperfluorescent OLEDs with Ultranarrow Emission

open access: yesAdvanced Optical Materials, EarlyView.
This work presents the development of efficient blue thermally activated delayed fluorescent (TADF) materials that perform well without doping, enabling simplified, matrix‐free hyperfluorescence (MFHF) OLEDs. When combined with encapsulated narrow‐band emitters, the TADF materials serve as effective hosts resulting in pure blue, ultranarrow emission ...

Bubble Printing of Anisotropic Clay Nanotubes

open access: yesAdvanced Optical Materials, EarlyView.
Bubble printing patterns of lyotropic liquid crystal nanotubes form toroidal or linear patterns depending on laser movement and colloidal stability. Long nanotubes create radial filament bundles, while poor electrostatic repulsion hinders deposition.
