Diamonds containing nitrogen-vacancy (NV) centers possess unique quantum properties, such as long spin relaxation times, that enable quantum sensing and highly sensitive measurements. In particular, nanodiamonds (NDs) with NV centers are promising candidates for quantum biosensors capable of detecting magnetic and electrical signals induced by biological phenomena. Such applications require not only a high fluorescence intensity and long spin coherence times, but also a high ODMR contrast, good colloidal dispersibility, uniform particle size, and consistent morphology. In this study, we investigated the correlation between the fluorescence intensity, the optically detected magnetic resonance (ODMR) contrast, and the concentration of NV centers in NDs under different electronirradiation temperature conditions—specifically, high temperature (HT) and room temperature (RT). |
