RADIATION-INDUCED COLORATION IN GLASS

PDF Version Also Available for Download.

Description

General aspects of radiation-induced coloration in glass are discussed. It is considered that the most significant initial effect of the radiation is to produce free electrons and positive holes in a track. The decay of the track from the initial condition is described in some detail, assuming that the rate of diffusion of electrons from the track is small compared to the rates of other processes, and that primary'' processes which form color centers can be considered independent of secondary'' processes which cause destruction of color centers. A method of calculation is described which gives the concentration of color centers ... continued below

Description

General aspects of radiation-induced coloration in glass are discussed. It is considered that the most significant initial effect of the radiation is to produce free electrons and positive holes in a track. The decay of the track from the initial condition is described in some detail, assuming that the rate of diffusion of electrons from the track is small compared to the rates of other processes, and that primary'' processes which form color centers can be considered independent of secondary'' processes which cause destruction of color centers. A method of calculation is described which gives the concentration of color centers formed at various doses. With plausible assumptions for the parameters, agreement with the data of Schulman on a silver phosphate glass is obtained. The treatment of glasses less simple than the silver phosphate case is also discussed. (auth)
