IMPROVED LOW EMISSIVITY COATING WITH OPTIMAL BASE LAYER MATERIAL AND LAYER STACK

摘要

A method for making low emissivity panels, including forming a base layer to promote a seed layer for a conductive silver layer. The base layer can be an amorphous layer or a nanocrystalline layer, which can facilitate zinc oxide seed layer growth, together with smoother surface and improved thermal stability. The base layer can include doped tin oxide, for example, tin oxide doped with Al, Ga, In, Mg, Ca, Sr, Sb, Bi, Ti, V, Y, Zr, Nb, Hf, Ta, or any combination thereof. The doped tin oxide base layer can influence the growth of (002) crystallographic orientation in zinc oxide, which in turn serves as a seed layer template for silver (111).
