, et al.. Growth and characterization of nanodiamond layers prepared using the plasma-enhanced linear antennas microwave CVD system. Journal of Physics D: Applied Physics, IOP Publishing, 2010, 43 (37) Abstract. Industrial applications of PE CVD diamond grown on large area substrates, 3D shapes, at low substrate temperatures and on standard engineering substrate materials require novel plasma concepts. Based on the pioneering work of the group at AIST in Japan, highdensity coaxial delivery type of plasmas have been explored [1]. However, an important challenge is to obtain commercially interesting growth rates at very low substrate temperatures. In the presented work we introduce the concept of novel linear antenna sources, designed at Leybold Optics Dresden, using high-frequency pulsed MW discharge with a high plasma densitiy. This type of pulse discharges lead to the preparation of nanocrystalline diamond thin films, compared to ultra-nanocrystalline diamond thin films prepared in Ref [1]. We present OES data for the CH 4 -CO 2 -H 2 gas chemistry and we discuss the basic properties of the nanocrystalline diamond (NCD) films grown.

Nanodiamond is a novel and promising material for in vitro and in vivo imaging in living cells. In this work, we studied (using quantum chemical calculation methods) how the various surface terminations affect the conditions for the fluorescence of nitrogen-vacancy (NV) centers in nanodiamond particles. We worked with clusters containing between 35 and 86 atoms of carbon containing NV centers with different charge states of their vacancies (NV À and NV 0 ) and with different terminations: OH, H, NH 2 , carbonyl, carboxyl, and hydroxyl groups. The systems under study were modeled by DFT-based calculations using the Gaussian 09 and Turbomole-5.10 program packages. ß 2010 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheimo 2048 I.
