Title
(EN) TREATMENT METHOD FOR OPTICALLY TRANSMISSIVE BODY
(FR) PROCÉDÉ DE TRAITEMENT D'UN CORPS OPTIQUEMENT TRANSMISSIF
Abstract
(EN)
A method of treating a transmissive body of zinc sulfide or zinc selenide includes placing a non-platinum metal layer, such as a layer of cobalt, silver, or iron on a surface of the transmissive body, and improving the optical properties of the transmissive body by subjecting the body and the layer to an elevated temperature and elevated pressure. The zinc sulfide or zinc selenide may be chemical vapor deposited material. The non-platinum metal of the layer may be such that a Gibbs free energy of formation of a most stable sulfide (or selenide) of the non-platinum metal is more negative than a Gibbs free energy of formation of a most stable zinc sulfide (or zinc selenide) configuration that is thermodynamically capable of reacting with the non-platinum metal.
(FR)
L'invention concerne un procédé de traitement d'un corps transmissif de sulfure de zinc ou de séléniure de zinc qui comprend le placement d'une couche de métal qui n'est pas le platine, telle qu'une couche de cobalt, d'argent ou de fer sur une surface du corps transmissif, et l'amélioration des propriétés optiques du corps transmissif en soumettant le corps et la couche à une température élevée et à une pression élevée. Le sulfure de zinc ou le séléniure de zinc peut être un matériau déposé chimiquement par vapeur. Le métal de la couche qui n'est pas le platine, peut être tel qu'une énergie libre de Gibbs de formation d'une configuration de sulfure (ou séléniure) la plus stable du métal, qui n'est pas le platine, est plus négative qu'une énergie libre de Gibbs de formation d'une configuration de sulfure de zinc (ou séléniure de zinc) la plus stable qui peut thermodynamiquement réagir avec le métal qui n'est pas le platine.
