Co‐Solvent‐Aided Opto‐Thermophoretic Printing of Gold Nanorod Assemblies
A focused laser beam creates a thermal gradient, driving the gold nanorods and polymer coils toward the heated region of the glass substrate, i.e, the laser spot. After the adsorption of the polymer on the gold surface, the nanorods start to assemble onto the surface in a ring‐shaped pattern that grows radially until the beam is turned off.

Optical Properties of Thin Films of Tin Iodide Perovskite Nanostructures
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
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.

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 ...

Enhanced Two‐Photon Excited Emission of Quantum Emitters by Colloidal Plasmonic Metasurfaces
Colloidal plasmonic metasurfaces presenting a completely exposed optical cavity are fabricated via templated self‐assembling silver nanoparticles into squared arrays on top of a thin film of CdSe/ZnS quantum dots. The resulting structure promotes the enhancement of the two‐photon absorption and emission processes of the quantum emitter by exploiting ...
