Comparative study of thermostimulated luminescence and electron emission of nitrogen nanoclusters and films Conference Paper uri icon

abstract

  • We have studied thermostimulated luminenscence and electron emission of nitrogen films and nanoclusters containing atomic nitrogen free radicals. Thermostimulated electron emission from N2 nanoclusters was ob-served for the first time. Thermostimulated luminescence spectra obtained during N2-He sample destruction are similar to those detected from N 2 films pre-irradiated by an electron beam. This similarity reveals common mechanisms of energy transfer and relaxation. The correlation of the luminescence intensity and the electron cur-rent in both systems points to the important role of ionic species in relaxation cascades. A sublimation of solid helium shells isolating nitrogen nanoclusters is a trigger for the initiation of thermostimulated luminescence and electron emission in these nitrogen-helium condensates.
