A low-E coating has good color stability (a low &#x394;E* value) upon heat treatment (HT). Thermal stability may be improved by the provision of an as-deposited crystalline or substantially crystalline layer of or including zinc oxide, doped with at least one dopant (e.g., Sn), immediately under an infrared (IR) reflecting layer of or including silver; and/or by the provision of at least one dielectric layer of or including an oxide of zirconium. These have the effect of significantly improving the coating's thermal stability (i.e., lowering the &#x394;E* value). An absorber film may be designed to adjust visible transmission and provide desirable coloration, while maintaining durability and/or thermal stability. The dielectric layer (e.g., of or including an oxide of Zr) may be sputter-deposited so as to have a monoclinic phase in order to improve thermal stability.

A low-E coating has good color stability (a low &#x394;E* value) upon heat treatment (HT). The provision of an as-deposited crystalline or substantially crystalline layer of or including zinc oxide, doped with at least one dopant (e.g., Sn), immediately under an infrared (IR) reflecting layer of or including silver in a low-E coating has effect of significantly improving the coating's thermal stability (i.e., lowering the &#x394;E* value). One or more such crystalline, or substantially crystalline, layers may be provided under one or more corresponding IR reflecting layers comprising silver.

Thermal stability may be improved by the provision of an as-deposited crystalline or substantially crystalline layer of or including zinc oxide, doped with at least one dopant (e.g., Sn), immediately under an infrared (IR) reflecting layer of or including silver; and/or by the provision of at least one dielectric layer of or including at least one of: (a) an oxide of silicon and zirconium, (b) an oxide of zirconium, and (c) an oxide of silicon. These have the effect of significantly improving the coating's thermal stability (i.e., lowering the &#x394;E* value).
