Abstract
In all-optical quantum sensing with fluorescent nanodiamonds (FNDs), enhancing the optical signal from excited FNDs is essential. Here, we demonstrate that the template-assisted assembly of FNDs allows the positioning of aggregated FNDs and improves the precision of temperature measurement. Our assembly process combines a polydimethylsiloxane microfluidic device with vertical through-holes and degas operation, enabling not only the aggregation of FNDs for increasing fluorescence intensity but also their high yield positioning over millimeter-scale areas.
