Highly stable films containing semiconductor nanoparticles ('quantum dots') are prepared from resins containing a fast-curing inner phase having a high glass transition temperature (T) and certain inner phase/outer phase combinations. The resins may comprise an inner phase and outer phase (but may appear to be a single phase due to their homogeneous appearance when viewed using an optical microscope). The method provides a highly scalable and cost-effective procedure for preparing films that are resistant to light, elevated temperatures, moisture, and oxygen.

Highly stable quantum dot-containing polymer films

A composition of matter comprises a plurality of quantum dots and a metal thiol polymer that acts to stabilize the quantum dots. In certain embodiments, the metal thiol polymer is a zinc thiol polymer. The zinc thiol polymer may be a zinc alkanethiolate. The zinc alkanethiolate may be zinc dodecanethiolate (Zn-DDT). A composition comprising a plurality of quantum dots and a metal thiol polymer may be formulated with one or more additional polymers as a quantum dot-containing bead or as a quantum dot-containing composite material&#x2014;e.g., a multilayer film.
