プレポリマ組成物、発光デバイスを準備するための方法及び発光デバイス

摘要

Disclosed is a light emitting device comprising a device which serves as a primary light source. The light emitting device further comprises a population of photoluminescent quantum dots disposed in a host matrix, wherein the host matrix comprises at least a first layer. At least a portion of the quantum dots have a band gap energy smaller than the energy of at least a portion of the light produced by the source. The matrix is disposed so as to allow the light from the source to pass therethrough. As a result the quantum dots to photoluminesce light of a color characteristic of their sizes.
