Congrats to Physics Graduate Student Sonal Singh
Congratulations to Sonal Singh and co-authors for their recently accepted manuscript. The paper entitled ”Spatially Controlled Fabrication of Brightly Fluorescent Nanodiamond-Array with Enhanced Far-Red Si-V Luminescence” (by Sonal Singh, Vinoy Thomas, Dmitri Martyshkin, Veronika Kozlovskaya, Eugenia Kharlampieva, and Shane Catledge) will appear in the JournalNanotechnology. The paper will be available online to readers at http://iopscience.org/. This work demonstrates a novel approach to precisely pattern fluorescent nanodiamond-arrays with enhanced far-red intense photostable luminescence from silicon-vacancy (Si-V) defect centers.The precision-patterned pre-growth seeding of nanodiamonds is achieved by a scanning probe “Dip-Pen” nanolithography technique using electrostatically-driven transfer of nanodiamonds from “inked” cantilevers. The enhanced emission from nanodiamond-dots in the far-red is achieved by incorporating Si-V defect centers in subsequent chemical vapor deposition treatment. The authors anticipate that the far-red intense photostable luminescence (~738 nm) observed from Si-V defect centers integrated in spatially arranged nanodiamonds could be beneficial for the development of the next generation fluorescent based devices and applications.
