ZnS/Me heat mirror systems

Abstract

The spectral selective transmission and heat conservation efficiency of some heat mirror systems consisting of ZnS/Me (Me equals Al or Ag) under a different configuration have been studied. It is shown that the 15nmZnS/20nmAg system has optimistic spectral selective transmission in visible wavelength range and the highest reflection in infrared wavelength range. Ag can keep its optical characteristic after heating to 200 degree(s)C by the protecting thick layer of ZnS. The system consisting of 15nmZnS/10nmAl is the efficiency heat mirror in the ZnS/Al systems. It is a cheaper material in application although it cannot compare with ZnS/Ag systems.
