Abstract

The problem of microdefects (or colour centers) in transparent glasses is very actual now. In a more common sense this question connects with the fundamental aspects of a glass structure. As the confirmation of such proposal it must be mentioned about the presence of a mutually exclusive model of silica glasses. The most known theories operate with local microdefects, such as non-bridged oxygens or ring groups in silica network, but the same physical experiments were used to establish the microclaster model (see Ref. ¹ and references therein). In a last case the term "defect" is absent at all. So, the formulation of the new spectroscopic tools for glass structure investigation is needed.
