Abstract

The optical properties of metals, and particularly their high reflectivity, are related to the effect on their free electrons of the energy of the incident light, but a satisfactory explanation of the characteristic colours of gold and its alloys and intermetallic phases has become possible only since calculations could be made of energy band structures.
