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.

High‐Detectivity GeSn Mid‐Infrared Photodetectors for Sensitive Infrared Spectroscopy

open access: yesAdvanced Photonics Research, EarlyView.
This work introduces a complementary metal‐oxide‐semiconductor (CMOS)‐compatible, high‐detectivity mid‐infrared GeSn photodetector monolithically integrated on a silicon platform. Enabled by an innovative composition‐gradient GeSn buffer, the high‐quality, thick GeSn active layer delivers exceptional responsivity and detectivity across the mid‐infrared

Tuning Surface Phonon Polaritons in One‐Dimensional Complementary Nanostructures via Curvature and Dielectric

open access: yesAdvanced Photonics Research, EarlyView.
Curvature and dielectric is introduced to tune properties of surface phonon polaritons (SPhPs) in complementary nanostructures: nanowire (NW) and nanohole (NH). It is found that NH complements the frequency band range of SPhP of NW. Frequency‐band subinterval of the SPhP in NHs and NWs can be tuned by dielectric.
