Pressure‐Induced Structural and Optoelectronic Modulations in 2D Dion‐Jacobson Hybrid Lead Iodide Perovskites With a Rigid Spacer

Advanced Optical Materials, EarlyView.
Compression to ≈2.0 GPa results in a non‐monotonic enhancement of the Pb‐I bond distortion, rarely observed in other 2D lead‐iodide hybrid perovskites. The octahedral distortion together with the rigidity of spacer cation are found to play a dominant role in determining the optoelectronic properties of DPDAPbI4 under high pressure.

Liquid Metal‐Exfoliated SnO2‐Based Mixed‐Dimensional Heterostructures for Visible‐to‐Near‐Infrared Photodetection

Advanced Optical Materials, EarlyView.
Two dimensional (2D) atomically thin materials hold significant promise for next‐generation photodetectors but are limited by low light absorption and scalability challenges. This study presents a high‐performance photodetector integrating liquid metal‐derived 2D SnO2 with CdTe, enabling efficient visible to near‐infrared detection and offering a ...

In Situ Transformation of Electrum Nanoclusters Embedded in Polymer Matrices Exhibit Near‐Infrared Emission With Quantum Yield Exceeding 70%

Advanced Optical Materials, EarlyView.
The AuAgNCs@OSTE nanocomposite, fabricated using off‐stoichiometric thiol‐ene polymerization, incorporates Au23‐xAgx(SAdm)15 nanoclusters and OSTE monomer. After UV curing, it reaches a maximum PLQY of 73% at 740 nm after 20 h of UV curing. After 72 h UV curing, PLQY reaches 60% at 850 nm, with minimal reabsorption losses due to the higher Stokes shift.

Miniaturized Single‐Photon Level Computational Complex Field Imaging System via Meta‐Optics

Advanced Optical Materials, EarlyView.
8192 Hadamard mask patterns generated by the digital micromirror device (DMD) are projected onto a micro target sample via a metalens. The corresponding modulated intensity spectrum encoded with the spatial information of the target is then captured by a photomultiplier tube (PMT) at the Fourier plane to recover both the amplitude and phase images ...
