摘要： LED devices emitting white light comprise a blue-emitting LED, green-emitting quantum dots (QDs) and red-emitting K2SiF6:Mn4+ (KSF) phosphor. A backlight unit (BLU) for a liquid crystal display (LCD) comprises one or more blue-emitting LEDs and a polymer film containing green-emitting QDs and KSF phosphor. The QDs and/or KSF phosphor may be encapsulated in beads that provide protection from oxygen and/or moisture.

摘要： 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.
