Bridging Boltzmann and Non‐Boltzmann Optical Thermometry Enabled by Multimodal Perovskite Nanocrystals

Advanced Optical Materials, EarlyView.
Multimodal perovskite nanocrystals enable optical thermometry across multiple excitation and emission regimes, spanning the UV–Vis–NIR spectral range. By combining upconversion, downshifting, and persistent luminescence, the platform bridges conventional Boltzmann and non‐Boltzmann thermometric approaches.

Color Center Formation in Silicon‐On‐Insulator for On‐Chip Photonic Integration

Advanced Optical Materials, EarlyView.
ABSTRACT Color centers in silicon have great potential as single photon sources for quantum technologies. Some of them – like the T center – also possess optically‐active spins that enable spin‐photon interfaces for generating entangled photons and multi‐spin registers. This paper explores the generation of several types of color centers in silicon for

Unraveling and Mitigating Resolution Loss in UV‐Assisted Vapor Phase Polymerization of Monolithic PEDOT:Tosylate Electrochromic Patterns

Advanced Optical Materials, EarlyView.
This work aims to understand the origin of pattern deviation in PEDOT:Tos films formed via vapor phase polymerization on UV‐exposed oxidant. UV exposure induces formation of loosely bound water which diffuses and produces macroscopic structuring at increased block copolymer contents.

Micromachined Double‐Membrane Mechanically Tunable Metamaterial for Thermal Infrared Filtering

Advanced 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
