Optical Properties of Thin Films of Tin Iodide Perovskite Nanostructures

Advanced Optical Materials, EarlyView.
A comprehensive spectroscopic study of thin films of 3D CsSnI3 nanocrystals (NCs) that coexist with residual 2D Ruddlesden‐Popper nanosheets (NSs) has been performed. Polymer encapsulation enables solid‐state stabilization of the tin iodide perovskite nanostructures, while insight into the energetics and dynamics of the NC and NS excitons is provided ...

Carbonized Polymer Dots‐Based Spectrally Adaptable Photonic Microbarcodes

Advanced Optical Materials, EarlyView.
This study explores spectrally tunable photonics barcodes using carbonized polymer dots (CPDs) based on whispering gallery mode (WGM) photoluminescence. CPDs offer wavelength‐dependent emission from visible to near‐infrared (NIR), thereby enabling variable WGM emissions.

Pyroelectric Doping Reversal of MoS₂ p‐n Junctions on Ferroelectric Domain Walls Probed by Photoluminescence

Advanced Optical Materials, EarlyView.
The potential of pyroelectricity for controlling electron doping in monolayer MoS2 on periodically poled LiNbO3 substrates is demonstrated. Pyroelectric charges are shown to convert p‐n into n‐p homojunctions formed in MoS2 on domain walls. The variation in the MoS2 electron density from 300 to 10 K is consistent with the change in the spontaneous ...

Fabrication Optimization of van der Waals Metasurfaces: Inverse Patterning Boosts Resonance Quality Factor

Advanced Optical Materials, EarlyView.
An optimized fabrication approach for the nanostructuring of optical metasurfaces from van der Waals materials like hexagonal boron nitride is presented. The resonator geometries show enhanced geometric homogeneity, resulting in a significant increase in quality factors of symmetry‐protected bound states in the continuum resonances.

Optimization of ZnGa2O4:Cr3+ Nanoparticles Synthesis Exhibiting Persistent Luminescence for Nanoplastic Labelling and Imaging in Daphnia Magna

Advanced Optical Materials, EarlyView.
ZnGa2O4:Cr3+ nanoparticles with persistent luminescence are synthesized and optimized for labeling microplastics via cryomilling. The solvothermal method provides superior optical properties, enabling background‐free imaging. These luminescent particles are successfully used to trace microplastic uptake and distribution in Daphnia magna, offering a ...

Plasmonic Hot Spots on Topological Insulator Nanotips for Enhancing Light Interaction with MoS2 Atomic Monolayer [invited]

Advanced Photonics Research, EarlyView.
A pair of Sb2Te3 topological insulator (TI) nanotips is fabricated by using the focused ion beam lithography to demonstrate the plasmonic hot spot effect at the visible range. The strong enhancement of electric field can be generated on the TI nanotips due to the plasmonic effect, giving rise to the obvious improvement of photoluminescence emission ...
