Abstract
New aluminate glasses were obtained with the conventional melt-quench technique in the system SrO-ZnO-Al2O3. The glass forming region was determined. The glasses were colorless and had good chemical durability in laboratory conditions. When irradiated with UV-light, a broad absorption was induced with a peak at 470nm (2.64eV) and an ESR signal (77K and 300K) was induced with an apparent g-value of 2.006. Both the changes in optical density and the intensity of the ESR signal increased with the ZnO content. From the characteristic of ESR signal, coloring of glass was concluded to a due to the formation of hole trapped on oxygen and electron center resting on zinc ions.
