Until recently, the number of emission colors available from fluorescent
diamond particles was primarily limited to red to near-infrared
fluorescence from the nitrogen-vacancy color center in type Ib synthetic
diamond and green fluorescence associated with the
nitrogen-vacancy-nitrogen center in type Ia natural diamond. Using our
recently reported rapid thermal annealing technique, we demonstrate the
capability of producing fluorescent diamond particles that exhibit
distinctive blue, green, yellow, and red fluorescence from the same
synthetic diamond starting material. Utilizing these multiple colored
diamonds, we analyze their fluorescence characteristics both in-solution
as well as on-substrate and additionally evaluate their viability in
simple multiplex imaging and cellular bioimaging experiments. While
there are still challenges associated with their immediate use in
traditional multiplex imaging, this novel approach opens new
opportunities to enhance the capability and flexibility of fluorescent
diamond particles at the nanoscale.
