Optimizing Metamaterial Inverse Design with 3D Conditional Diffusion Model and Data Augmentation

open access: yesAdvanced Materials Technologies, EarlyView.
A generative AI model, the 3D conditional diffusion model (3D‐CDM), is introduced to enhance the inverse design of voxel‐based metamaterials. A data augmentation technique based on topological perturbation expands the dataset, further improving generation quality and accuracy.

All‐Optically Driven Optofluidic Light Modulator

open access: yesAdvanced Optical Materials, EarlyView.
In this work, an all‐optically driven optofluidic light modulator is developed, based on the optical actuation of waveguided beams by liquid crystals confined in a microfluidic channel. The photovoltaic effect in lithium niobate is employed to control the alignment of the liquid crystal in the microfluidic channel underneath by a light‐induced electric

Purinylidene‐Based Iridium(III) Phosphors for Efficient Purple Phosphorescence and Organic Light‐Emitting Devices

open access: yesAdvanced Photonics Research, EarlyView.
A family of purinylidene based Ir(III) emitters, namely, f‐ct2a–d, are synthesized and utilized as both dopants and sensitizers in the construction of efficient purple to deep‐blue organic light‐emitting diode devices. It is very challenging to achieve highly efficient and low roll‐off purple to deep‐blue organic light‐emitting diodes (OLEDs) due to ...
