Abstract
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—e.g., a multilayer film.
