Аннотация:The dependence of lead silicate glass color, applied using copper(II) ions, on lead content in the glass, the nature of the alkali metal, and copper content was studied. It was shown that the principal contribution to the color is made by the shift of the fundamental absorption edge, which correlates with the amount of lead and copper ions. According to EPR results for glasses with the studied compositions, copper ions have a tetragonally distorted octahedral coordination environment, which does not change considerably with composition. The CuII d—d-transition bands also do not undergo considerable changes.
