SWITCHABLE HYDRIDE SMART WINDOW AND THE METHODS FOR PROCUDING THE SAME

A switchable hydride smart window solid thin film coating having variable opacity and the methods for producing the same is described. The coating includes the following layers deposited on substrate such as glass : a switchable layer, an optional barrier layer, a catalyst layer, an optional barrier layer, a solid electrode, an ion storage layer, an optional insulating layer and a transparent conductor layer. The switchable layer is preferably formed of a magnesium alloy and ore preferable, a ternary alloy of magnesium along with two additional rare earth metals such as yttrium (Y) and Titanium (Ti), i.e., MgYTi.
