Direct‐Write Printing of Multicolor Electroluminescent Films for Stretchable Display

open access: yesAdvanced Materials Technologies, EarlyView.
This work presents a mask‐free, fully printable alternating‐current electroluminescent (PACE) film using a direct‐write printing strategy. The multicolor PACE film, available in blue, green, and orange, reaches a thickness of ≈150 µm and achieves 180 cd m⁻2 at 6 V µm⁻¹.

Comparative Test of Novel Fluorescent Optical Antennas for LED‐ and Laser‐Based Optical Wireless Communications

open access: yesAdvanced Optical Materials, EarlyView.
New fluorescent optical antennas are realized and tested for diverse Optical Wireless Communication (OWC) applications. The fluorescent concentrator slabs, based on different organic fluorophores, convert and convey the digital data conveyed through intensity modulation of incoming light toward a small‐area photodiode.

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.

Large Bidirectional Refractive Index Change in Silicon‐rich Nitride via Visible Light Trimming

open access: yesAdvanced Optical Materials, EarlyView.
Continuous‐wave visible light trimming of PECVD silicon‐rich nitride micro‐ring resonators enables precise, large bidirectional refractive index tuning. Resonance shifts as fine as 10 pm are achieved with a cost‐effective setup, demonstrating large red shifts of 49.1 nm and blue shifts of 10.6 nm.
