V originále
Atmospheric pressure dielectric barrier discharge (DBD) in Ar/H-2 gas feed with C2H2 or CH4 admixture was studied at room and high temperature of 680 degrees C by plasma diagnostics (electrical measurements, fast camera imaging, and optical emission spectroscopy). It was shown that filamentary DBD in pure Ar or Ar/H-2 can be converted into homogeneous discharge by an acetylene admixture. Fast intensified charge-coupled device (ICCD) camera proved that this homogeneous discharge is an atmospheric pressure glow discharge (APGD) at room temperature whereas at high temperature the discharge mode switches at every half-period between APGD and atmospheric pressure Townsend discharge. The high temperature discharges (610-710 degrees C) in Ar/H-2/C2H2 and Ar/H-2/CH4 were also investigated with respect to a surface bound deposition of carbon nanotubes using 5 nm thick iron layer as a catalyst. CNTs were deposited without any dedicated catalyst pretreatment phase. The quality of CNTs, namely, their density, vertical alignment, and width of the diameter distribution, was better for the C2H2 gas feed and higher temperatures. (C) 2015 AIP Publishing LLC.

Bariérový výboj za atmosférického tlaku ve směsi Ar/H2 s příměsí C2H2 a CH4 byl studován za pokojové a vysoké teploty. Výboj za vysoké teploty (610-710°C) ve směsi Ar/H2/C2H2 a Ar/H2/CH4 byl studován za účelem růstu uhlíkových nanotrubek.
