Light-induced electron emission from silicone oils

Abstract

Light-induced electron emission from silicone fluids has been measured as a function of photon energy. Emission energy thresholds were determined. Taking into account published data on the photoconductivity energy threshold in these fluids, values for the polarization energy of the positive ion and for the energy of the electronic conduction level could be deduced. In addition, some gas phase ionization potentials were determined.
