NV centers in diamond have remarkable optical, electrical and magnetic properties. We report a unique method for synthesis of pure and nitrogen doped nanodiamonds at room temperatures and atmospheric pressure. Amorphous carbon films are deposited onto c-sapphire substrates using pulsed laser deposition (PLD) technique employing KrF nanosecond laser. N doped carbon films are formed by simultaneous bombardment with N2+ (0.5-1.0 KeV) ions using RF plasma. Subsequently, the films are irradiated with nanosecond laser pulses of ArF excimer laser having energy density 0.5-1.0Jcm-2 to form micro and nano structures of diamond. N atoms and vacancies are incorporated in the diamond lattice during the liquid phase growth. SEM, EBSD, Raman spectroscopy, TEM, and EELS are performed to characterize the samples. Electrical pumping of NV centers in diamond is also performed with the application of an external electric field in the presence of 532 nm laser, which have immense application in quantum computing.
