Magnetic Steganography Based on Wide‐Field Diamond Quantum Microscopy

Advanced Optical Materials, EarlyView.
This document illustrates magnetic steganography. Magnetic graphics, including pixel art and QR codes, are produced using magnetic materials (such as Ni) and obscure behind patterns manufactured using non‐magnetic materials (such as Au), which are unveiled through widefield quantum microscopy. Furthermore, manipulating the electron spin of NV with dual

Direct Growth of Rectangular 2D Layered Metal‐Halide Perovskite Microcrystal Photonic Cavities on Functional Substrates

Advanced Optical Materials, EarlyView.
A simple and scalable method to fabricate 2D layered metal halide microcrystals with rectangular shape, extremely flat surfaces, and submicron thickness is presented. The growth occurs in evaporating droplets on planar substrates, which enables the fabrication of the microcrystals directly on functional surfaces. The microcrystals demonstrate excellent

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 ...

Intracellular Monitoring of Luminescent Ag2S Nanoparticles in Fibroblasts

Advanced Optical Materials, EarlyView.
This study investigates the long‐term luminescence behavior of Ag2S quantum dots (AS QDs) with three surface ligands (DTDTPA, 11MUA, PEG) in fibroblasts over 9 days. AS‐PEG showed stable uptake and enhanced NIR‐II emission, while others decreased due to oxidative stress.

Resonance Energy Transfer and Purcell Effect in a Cu2O/Au Hybrid Optical Antenna

Advanced Photonics Research, EarlyView.
A Cu2O nanosphere mediates efficient (e.g., 70%) resonance energy transfer (RET) to a gold substrate. The RET damping constant derived from single‐particle scattering, ΓRET$\left(\Gamma\right)_{R E T}$, identifies interband transitions in Au. RET also occurs from an excited electron‐hole pair in Au to the Cu2O/Au hybrid resonator mode, followed by ...
