摘要

A method of preparing an insulating glass unit (IGU), the method comprising: providing a first glass substrate (1); arranging a plurality of layers, directly or indirectly, on a first main surface of the first glass substrate (1), including the plurality of layers, in order from the outside of the first glass substrate (1): a first layer (9b ) comprising silicon oxynitride having a refractive index of 1.5-2.1, a layer comprising ITO (5) having a refractive index of 1.7-2.1, and a second layer ( 9a) comprising silicon oxynitride having a refractive index of 1.5-2.1; heat treat the first glass substrate (1) with the plurality of layers disposed thereon; providing a second glass substrate (21) in separation and substantially parallel relationship, with respect to the first glass substrate, so that the first main surface of the first glass substrate is oriented outwardly from the second glass substrate; and jointly seal the first and second glass substrates.
