A polymer comprising one or more chalcogenide elements and one or more crosslinking moieties. The crosslinking moieties may be organic, inorganic, or both. Also disclosed is the related method for making a polymer comprising purifying a chalcogenide polymer powder comprising one or more chalcogenide elements, melting the purified chalcogenide polymer powder, adding one or more crosslinking moieties to the melted chalcogenide polymer, and curing the modified chalcogenide polymer at a temperature between 150 and 200° C.

Organically modified chalcogenide polymers

This disclosure concerns a method of making a ligand for Quantum Dot functionalization, a method of making a functionalized Quantum Dot (QD) with a ligand, and a method of making a transparent luminescent quantum dot thiol-yne nanocomposite with tailorable optical, thermal, and mechanical properties. The prepolymer solution and functionalized Quantum Dot can be used in additive manufacturing.

Fabrication of luminescent quantum dot thiol-yne nanocomposites with tailorable optical, thermal and mechanical properties

A bonded optical assembly comprising infrared-transparent materials. The assembly comprises two or more infrared transparent optical elements and a polymer comprising at least one chalcogenide element and crosslinking moieties between the infrared-transparent optical elements. The crosslinking moieties may be organic, inorganic, or both.

Organically modified chalcogenide polymers for use as optical adhesive materials

A method for bonding infrared transparent materials by placing a polymer comprising at least one chalcogenide element and crosslinking moieties between infrared-transparent optical elements and applying heat, pressure, or both. The crosslinking moieties may be organic, inorganic, or both. Also disclosed is the related bonded assembly comprising infrared transparent optical elements.

The present invention provides a method for synthesizing a new class of inorganic-organic polymeric materials. These polymers are made with a backbone comprising chalcogenide elements such as sulfur, selenium, and/or tellurium along with organic crosslinking moieties that determine its physical and optical properties. Also disclosed are the related polymeric materials. These polymers are suitable for optical applications in short wave infrared (SWIR, 1-3 &#x3bc;m) and mid wave infrared (MWIR, 3-8 &#x3bc;m) regions.
