Abstract
Coated articles are provided with an anti-reflective (AR) layer(s) system which enables reduced reflection, increased visible transmission, and/or neutral color. In certain embodiments, the AR layer(s) system includes a silicon nitride layer(s), a silicon oxynitride layer, and/or a silicon oxide layer on the substrate over an infrared (IR) reflecting layer(s) such as silver. The AR system surprisingly enables improved visible transmission and/or reflection to be combined with more neutral color.

A coated article including a coating supported by a glass substrate, the coating comprising:
- an infrared (IR) reflecting layer comprising silver sandwiched between first and second contact layers;
- a first dielectric layer having an index of refraction n<=3.0 provided between the IR reflecting layer and the glass substrate;
- a second dielectric layer comprising silicon nitride provided over the IR reflecting layer;
- a third dielectric layer comprising silicon oxynitride provided over the IR reflecting layer;
- wherein the second dielectric layer comprising silicon nitride is provided between the IR reflecting layer and the third dielectric layer;
- and
- a fourth dielectric layer comprising silicon oxide provided over the second and third dielectric layers.
A coated article including a coating supported by a glass substrate, the coating comprising:
