Light absorbing layer structure

摘要

A light-absorbing layered structure has a viewer turned front layer (S1) of a matrix containing dielectric metal oxide with embedded particles (M1) of electroconductive material in a primary average concentration, and a viewer turned away rear layer (S2) of a matrix containing embedded metal oxide particles (M2) of electroconductive material in a secondary average concentration which is more than the primary average middle concentration. The metal oxide includes niobium oxide, titanium oxide, molybdenum oxide, tungsten oxide or vanadium oxide.
