1. A multilayer structure comprising:

  • a plastic substrate;

    a first metal oxide layer on the plastic substrate;

    an infrared radiation reflection layer on the first metal oxide layer; and

    a second metal oxide layer on the infrared radiation reflection layer, wherein each of the first and the second metal oxide layers comprise one of doped and undoped ZnO deposited by arc plasma deposition in which zinc is evaporated into a thermal plasma and wherein the doped and undoped ZnO have a stoichiometric excess of oxygen.
