Optical Properties of Thin Films of Tin Iodide Perovskite Nanostructures

open access: yesAdvanced 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 ...

Improvement of Cu Ablation Efficiency Using GHz‐Burst Femtosecond Laser at 515 nm Wavelength

open access: yesAdvanced Photonics Research, EarlyView.
The green‐wavelength gigahertz (GHz)‐burst mode significantly improves the Cu ablation efficiency due to the interaction of subsequent intra‐pulses in a GHz‐burst with molten Cu. The superiority of the green‐wavelength GHz‐burst mode over the infrared‐wavelength one for a higher performance of Cu ablation at a smaller number of intra‐pulses is ...

Enhanced Two‐Photon Excited Emission of Quantum Emitters by Colloidal Plasmonic Metasurfaces

open access: yesAdvanced Photonics Research, EarlyView.
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 ...
