Color shift of high LSG low emissivity coating after heat treatment

摘要

Low emissivity panels can include a protection layer of silicon nitride on a layer of ZnO on a layer of Zn2SnOx. The low emissivity panels can also include NiNbTiOx as a barrier layer. The low emissivity panels have high light to solar gain, color neutral, together with similar observable color and light transmission before and after a heat treatment process.
