Near-Infrared Diamond Color Centers and Hybrid Nanodiamond Materials for Quantum Sensing

Fluorescent color centers in diamond have emerged as a powerful platform for emerging quantum technologies from quantum communication and computing to sensing. Most diamond color centers explored for applications today emit in the visible or near-infrared wavelength range below 900 nm, which is incompatible with long-distance fiber communication and outside the second near-infrared biological transparency window (1000 nm – 1700 nm, NIR-II)^[1]. At the same time, as quantum sensing technologies based on established visible color centers like the nitrogen-vacancy (NV) center mature, integrating diamond with other materials becomes critical for developing real-world applications. This presentation will discuss recent progress in two areas. 1. The discovery ^[2] and application^[3] of fluorescent near-infrared color centers in diamond. 2. The characterization of nanodiamonds containing NV centers^[4], their integration into functional materials like polymers^[5] and glass^[6], and their application in quantum sensing^[7].<br/><br/>References<br/>[1] P.
