Abstract

This paper reports on a microfluidic-assisted assembly of fluorescent nanodiamonds (FNDs) containing nitrogen-vacancy centers (NVCs) designed to enhance the sensitivity of temperature measurements through the zero-phonon line of the NVCs. Our vertically aggregated clusters of FNDs significantly enhanced the signal-to-noise ratio of the fluorescence and improved sensitivity. Furthermore, using approximately 100-nm FNDs for cluster fabrication reduces the temperature measurement error across clusters on a substrate. This vertical aggregation of FNDs at defined locations is used in all-optical temperature sensing applications where accurate temperature mapping is critical.
