We report the synthesis of nanocomposite films of bismuth nanoparticles (Bi NP) in a hydrogenated amorphous carbon, a-C:H, matrix. The bismuth nanoparticles were generated within a toroidal planar hollow cathode (TPHC) system using a pulsed DC power of 200 W, and the a-C:H was simultaneously produced by plasma enhanced chemical vapour deposition (PECVD) of acetylene, or methane, in the exit-plasma from the TPHC. The concurrent nanoparticle and amorphous film formation meant that the distribution of nanoparticles within the deposits was uniform and avoided problems of agglomeration of the nanoparticles. The advantage of this synthesis method is that any material which can be sputtered, including magnetic materials, can be used to produce the nanoparticle phase of the nanocomposite. The exhaust plasma from the TPHC can be used to simultaneously deposit the amorphous phase through a suitable plasma enhanced chemical reaction.
