Particle Collecting in a 13.56 MHz Radiofrequency Methane Discharge
Fig. 1: Particle trapping near the electrodes in RF methane plasma (RF = 80W, pressure 130 Pa and flow rate 5.6 sccm) put in evidence by laser light scattering: (a) under the RF electrode 200 s after the plasma is switched on, (b) above the grounded electrode 300 s after the plasma is switched on. The particle cloud form follows the electrical field lines. The authors are with the GREMI, Groupe de Recherches sur l'Energétique des Milieux Ionisés, UMR6606, CNRS/Université d'Orléans, Faculté de

Photoluminescence of hydrogen amorphous carbon nitrile particles obtained in a 13.56 MHz dusty plasma
International audienceIn this article, we report the photoluminescence (PL) of small particles generated in CH4/N2 radiofrequency (13.56 MHz) discharges. The particles have been produced with various mixtures of N2 and CH4 gases. The particle PL has been analysed using fluorescence microscopy in air with an Ar+ laser at 488 nm. It appears that the photoluminescence intensity is in relation to the particle size. However, the incorporation of nitrogen modifies the peak position of the PL spectrum
