In this work, diamonds with negative charged silicon‐vacancy (SiV−) centers have been designed for use as thermometers in biomedical applications. Multiparametric analysis of the emission characteristics of the SiV− centers provides extraordinary sensitivity for temperature detection in the physiological temperature range.

Tailored Diketopyrrolopyrrole Derivatives for Efficient Deep‐Red Organic Lasers
Tailored diketopyrrolopyrrole derivatives exhibit high stable amplified spontaneous emission with single or dual bands. Incorporated into distributed‐feedback lasers based on one‐ and two‐dimensional dichromated‐gelatin diffractive gratings, these materials provide a robust, flexible platform for integrated organic deep‐red light sources. ABSTRACT Deep‐

WS2 Micro‐Dome Single Photon Source in a Tunable Open Cavity
In this work, a single‐photon source based on WS2 micro‐domes is realized and integrated into an open, tunable optical microcavity. Single‐photon emission from the coupled emitter–cavity system is observed. Detailed analysis shows that a pronounced acoustic phonon emission sideband contributes specifically to the non‐resonant emitter–cavity coupling in

Deterministic Fractal Plasmonic Metasurfaces for Broadband Mid‐Infrared Molecular Biosensing
This image illustrates a sensing platform based on deterministic fractal plasmonic metasurfaces, designed to overcome the persistent trade‐off between sensitivity and spectral bandwidth in surface‐enhanced infrared absorption (SEIRA) spectroscopy. At the heart of the schematic is a hierarchical subwavelength gold aperture array featuring self‐similar ...

Direct nanoimprinting transforms mesoporous titania films into visible‐wavelength metasurfaces through a streamlined deposition‐and‐imprint process requiring no conventional lithography or etching. The resulting structures support pitch‐tunable guided‐mode resonances, symmetry‐controlled quasibound states in the continuum, structural‐color image ...
