Description
  • The photoluminescence of the plasma prepared polysilylanes from corresponding monomers, exemplified by poly[(methyl)phenylsilylane], is examined. For the preparation two quantitatively different plasmas, were used: radiofrequency discharge (13,5MHz)and microwave discharge (2,45 GHz) in the regime of electron cyclotron resonance. We concentrated on the conditions where the 1D features of the polymers were preserved. Results for both optimised groups of materials exhibit similar results: the exc itonic absorption band with maximum at 320- 360 nm, depending on the conditions of preparation. We explain the observed phenomena by the occurrence of the nano-sized 1D Si polymers embedded in 3D covalently bonded Si network.
