[摘要]：The specifics of energy exchange by nonrelativistic electrons (electron energy of similar to 10(2)-10(3) eV) during their travelling through a dielectric layer have been studied depending on the thickness of the layer applied on substrates with different parameters. Electron travelling across a dielectric (pyrene) layer with a thickness of up to 10 nm deposited on a metal (bismuth) mirror is accompanied by the following effects dependent on the dielectric-layer thickness and the electric parameters of the boundary: a nonmonotonic change in the pyrene luminescence intensity and variation in secondary electron emission.
