Spectroscopic Signatures of Doping in Thin Films of Semiconducting Single‐Walled Carbon Nanotubes

Small, EarlyView.
This review presents an overview of the spectroscopic changes of semiconducting single‐walled carbon nanotubes upon chemical, electrochemical or electrostatic doping. The presence of holes or electrons directly affects visible to far‐infrared absorption, near‐infrared fluorescence and electroluminescence as well as Raman spectra, which enables in‐situ ...

An entropy-controlled objective chip for reflective confocal microscopy with subdiffraction-limit resolution

Nature Communications, 2023
Planar diffractive lenses (PDLs) with optimized but disordered structures can focus light beyond the diffraction limit. However, these disordered structures have inevitably destroyed wide-field imaging capability, limiting their applications in ...

Phase and absorbance retrieval in X‐ray holographic microscopy under weak illumination using physics‐driven neural networks

Journal of Synchrotron Radiation, EarlyView.
A physics‐driven deep learning model enables single‐shot retrieval of 3D phase and absorbance from shot‐noise‐limited hard X‐ray holograms. Validated on both synthetic and experimental data, it provides robust reconstruction under weak illumination.X‐ray holographic microscopy is a three‐dimensional (3D) imaging technique for nanoscale‐resolution ...

The Generation of Equal-Intensity and Multi-Focus Optical Vortices by a Composite Spiral Zone Plate

Photonics
We propose a new vortex lens for producing multiple focused coaxial vortices with approximately equal intensities along the optical axis, termed equal-intensity multi-focus composite spiral zone plates (EMCSZPs).

Adaptive focal lengths in white light focusing Fresnel lenses enabled by reflective-type and phase-only spatial light modulator

Scientific Reports, 2023
Fresnel zone plates (FZPs) are widely used in integrated optical systems to meet new cutting-edge demands for photonic integration and device miniaturizing. However, their use in applications of cross-scale fabrication still faces several obstacles, such

Time-resolved X-ray microscopy of nanoparticle aggregates under oscillatory shear

, 2008
Of all current detection techniques with nanometer resolution, only X-ray microscopy allows imaging nanoparticles in suspension. Can it also be used to investigate structural dynamics?

Positive‐Tone Nanolithography of Antimony Trisulfide with Femtosecond Laser Wet‐Etching

Advanced Functional Materials, Volume 36, Issue 31, 16 April 2026.
A butyldithiocarbamic acid (BDCA) etchant is used to fabricate various micro‐ and nanoscale structures on amorphous antimony trisulfide (a‐Sb2S3) thin film via femtosecond laser etching. Numerical analysis and experimental results elucidate the patterning mechanism on gold (reflective) and quartz (transmissive) substrates.

Three‐dimensional Antimony Sulfide Based Flat Optics

Advanced Functional Materials, Volume 36, Issue 32, 20 April 2026.
This work presents the development of a grayscale electron beam lithography (g‐EBL) method for fabricating antimony trisulfide (Sb2S3) nanostructures with customizable 3D profiles. The refractive index of g‐EBL patterned Sb2S3 is determined based on the synergy of genetic algorithm and transfer matrix method.
