Webobservation of the dichroic effect is not well understood. Since the Lycurgus Cup studies, the dichroic effect has been observed and studied on several occasions with gold, silver and alloy nanoparticles, and has been attributed to nanoparticle size [5,6], shape [7], polarisation [8], etc. WebNot before centuries later this dichroic effect was explained. It was in 1990 using transmission electron microscopy when it was discovered that the cup's glass contained gold and silver alloy colloids [34]. Previously, in 1857, Michael Faraday reported the production of colloidal gold following the reduction of chloroaureate [35].
