Enhanced Performance 3‐D Printed PLA Parts through a Photo‐Initiator Mediated UV‐Curing

open access: yesAdvanced Materials Technologies, EarlyView.
This solvent‐free method enhances 3‐D printed PLA parts by incorporating photo‐initiators during fabrication, followed by up to 3 min UV treatment. This process improves PLA's mechanical properties, including a 64% increase in tensile strength, while addressing weak interlayer bonding and outdoor sensitivity.

(3+1)D Printing of Core–Clad Waveguide by Two‐Photon Polymerization

open access: yesAdvanced Materials Technologies, EarlyView.
Low‐loss, single‐mode core–clad optical waveguides are fabricated using a novel (3+1)D multiphoton polymerization technique in a hybrid resin. Precise laser power control and multi‐pass exposure enable refractive index engineering and reduce scattering. Raman spectroscopy confirms the correlation between polymerization and index change.

Red Multi‐Resonant Thermally Activated Delayed Fluorescence Emitters as Bioimaging Agents

open access: yesAdvanced Optical Materials, EarlyView.
Multi‐resonant thermally activated delayed fluorescence (MR‐TADF) emitters have attracted strong interest for use in electroluminescent devices due to their high photoluminescence quantum yield and narrowband emission. These properties, along with red emission, are also crucial for bioimaging probes.
