Mechanically Tunable Optical Response in Silicon Nanosphere Metasurface Fabricated via Bottom‐Up Process

open access: yesAdvanced Optical Materials, EarlyView.
A large area mechano‐tunable square lattice array of silicon nanospheres is fabricated by a bottom‐up process, and the capability to tune the lattice resonances by external strain is demonstrated. Spectrally overlapping the electric and magnetic dipole lattice resonances by mechanical strain induces the lattice Kerker effect and strongly suppresses the

Emerging Hydrochromic Metal Halide Perovskites

open access: yesAdvanced Optical Materials, EarlyView.
Hydrochromic metal halide perovskites (MHPs) are promising candidates for next‐generation smart optical materials owing to their excellent responsiveness, superior reversibility, and highly tunable emission. This review summarizes the latest progress in hydrochromic MHPs and provides general principles for the rational design of advanced hydrochromic ...

Triplet–Triplet Annihilation Photon Upconversion Toward UVC Energy Generation Using TIPS‐Benzene and a Heptazine Derivative

open access: yesAdvanced Optical Materials, EarlyView.
The TTA‐UC from visible/UVA to UVB/C is demonstrated by combining a heptazine derivative with TIPS‐benzene‐based emitters. The heptazine derivative has a triplet energy level high enough to sensitize the emitters. The introduction of bulky tert‐butyl substituents to the TIPS‐benzene emitter is a simple and powerful strategy for enhancing the TTA‐UC ...

Micromachined Double‐Membrane Mechanically Tunable Metamaterial for Thermal Infrared Filtering

open access: yesAdvanced Photonics Research, Volume 6, Issue 5, May 2025.
Herein, a mechanically tunable double‐layer plasmonic metamaterial leveraging the extraordinary optical transmission effect observed in subwavelength arrays of openings within thin metal layers is presented. The concept is experimentally validated by integrating the proposed metamaterial structure into an electrostatic parallel‐plate actuator to create
