Mechanoluminescence of Bi‐Activated NaYGeO4 Polycrystals and 3D Printed Scaffolds in the NUV/Blue and NIR Spectral Range

open access: yesAdvanced Optical Materials, EarlyView.
NUV/Blue and NIR emitting mechanoluminescent (ML) materials based on a Bi‐doped germanate compound (NYGOBx) are reported. 3D‐printing is used to fabricate complex scaffold devices from this material, suggested for use as mechanically‐activated light sources for functional illumination.

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 ...

Carbonized Polymer Dots‐Based Spectrally Adaptable Photonic Microbarcodes

open access: yesAdvanced 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.

Local Tuning of the Epsilon‐Near‐Zero Condition in Hybrid Silicon Waveguides Using Reactive Laser Annealing

open access: yesAdvanced Photonics Research, EarlyView.
This work demonstrates the use of reactive laser annealing to selectively tune the epsilon‐near‐zero condition of tin‐doped indium oxide patches integrated in silicon waveguides. This postgrowth annealing technique enables flexible control over the optical constants of transparent conducting oxides (TCOs) at critical telecom wavelengths, paving the way
