Abstract
Photo-thermo-refractive (PTR) glass is a silica sodium aluminium zinc glass containing oxygen and fluorine as anions and four dopants, such as Ce, Ag, Sb and Sn, in which concentrations vary in the range of 0.1-0.01%. The main photochemical reaction occurring during the hologram recording (UV irradiation) is an electron transfer from Ce3+ to Ag+, which results information of Ag containing particles. Further thermal development causes the growth of NaF crystals on Ag particles. The main goal of this work was to elaborate the method of the luminescence analysis of PTR glass, and to find and identify the excitation and emission spectra of each dopant in PTR glass. All four dopants have excitation and emission spectra overlapping each other. In order to separate them, seven melts of PTR glass matrix without any dopants and with one or two dopants have been made. Each dopant has been added in the same concentration as it appears in a regular PTR glass. It was found that luminescence of Ce3+ has the highest intensity and masks the other dopants, except one of Sb3+. This work enables the further study of the behaviour of dopants in PTR glass matrix on each step of hologram writing.
