The optical properties of dichroic doped NCS glasses - Sergey Klimonsky - Moscow State University

Abstract

Sergey Klimonsky

The Lycurgus cup, a wonderful illustration of a late roman glass, is well known for its dichroism, that is, the capacity to alter shading relying upon the course of light. It is cut from a piece of NCS glass, containing limited quantities of iron, calcium, and phosphorus, silver and gold. In the wake of striking the glass is hazy, being red ink sent light and green in mirrored light. The optical properties of the glass are generally clarified by light retention and dispersing by bimetallic AgAu nanoparticles.
