    Abstract: A method is provided for producing an article which is transparent to infrared radiation. The method includes the steps of (a) disposing a plurality of nanoparticles on a substrate, wherein said nanoparticles comprise a metal sulfide or a metal selenide; (b) subjecting the nanoparticles to spark plasma sintering, thereby producing a sintered product; and (c) removing the sintered product from the substrate as a self-supporting mass.

    Abstract translation: 提供了一种制造对红外线辐射透明的物品的方法。 该方法包括以下步骤：（a）在基底上设置多个纳米颗粒，其中所述纳米颗粒包含金属硫化物或金属硒化物; （b）对纳米颗粒进行放电等离子体烧结，从而制备烧结产品; 和（c）作为自支撑块从基板上除去烧结产物。

    Abstract: A method is provided for producing an article which is transparent to infrared radiation. The method includes the steps of (a) disposing a population of nanoparticles on a substrate, wherein the population of spherical nanoparticles has a population variance of less than 10% in at least one parameter selected from the group consisting of diameter and maximum dimension; (b) subjecting the nanoparticles to spark plasma sintering, thereby producing a sintered product; and (c) removing the sintered product from the substrate as a self-supporting mass.
