Directed Synthesis/Fabrication and Surface Modification of IR Window Materials for the 8-14 Micron Region.

Abstract

Nearly monosize particles of pure NaLaS2 have been made by a sulfide fused salt technique. Such particles promise easier compaction and HIPing to highly dense IR window material. The increased fracture toughness of glass substrates due to the addition of a thin compressive overlayer has been measured. The fracture toughness appears to increase linearly with the total film stress and is independent of the film thickness necessary to provide that stress. Keywords include: Infrared, Transmitting, Chalcogenides, and Thin films.
