Abstract

The energetics of the glass structure glasses characterizing the magnitude of the "cation-oxygen" bond constitutes the key factor which determines the quantity of charge stored. In the successive replacement of cation-modifiers, most charge is stored in those glasses in which the lowest concentration of hole color centers is produced. In the event of a percentage change in the content of the cation-modifier in the glass structure, most charge is stored in those glasses that lie closest to the metaphosphate line. A law of charge storage in phosphate glasses has been established. The kinetics of charge storage is more complex: a rapid increase in the quantity of charge stored is observed in the first stage of storage, whereas in the second stage the quantity of charge stored is observed to decrease slowly at large doses. Analysis of the curves indicates two processes occurring in the glasses during irradiation. The mechanism of neutralization of electrically active centers consists in a neutral P2O7 complex being formed from the charged radicals PO3- and PO4{right double angle bracket}.
