Photochromic charge transfer processes in natural pink and brown diamonds
In this paper we explore the way Argyle pink diamonds can change their colour when exposed to ultraviolet, visible and infrared light sources. The crystal defect that is responsible for the diamond’s pink colour is a complete mystery: our measurements provide new information about its nature and also allow us to develop a model that explains how the colour change occurs when electrons jump from the “pink defect” to several other known defects in the diamond crystal.
