Upconversion nanocrystal quantum optical sensors for high-pressure applications
Developed at North Carolina State University, this innovative sensor uses upconversion nanocrystals for high-pressure quantum optical sensing. It offers robust, all-optical connections, minimal insertion limitations, and high-speed operation, ideal for dynamic environments.
Overview
The upconversion nanocrystal quantum optical sensor is a cutting-edge technology developed to detect high-pressure environments using rare earth doped materials. These materials exhibit unique upconverted fluorescent emission lines, which shift linearly with pressure-induced changes in quantum ground states. This sensor system leverages a vast array of nanoparticles for parallel sensing, ensuring high robustness and sensitivity. Its design includes a compact sensor head with optical fibers facilitating excitation and emission collection, offering a minimalistic and efficient solution for high-pressure sensing applications.
