Abstract
Multi-phase polymer films of quantum dots (QDs) and their use in light emitting devices (LEDs) are disclosed. The QDs are absorbed in a host matrix, which dispersed within an outer polymer phase. The host matrix is hydrophobic and is compatible with the surface of the QDs. The host matrix may also include a scaffolding material that prevents the QDs from agglomerating. The outer polymer is typically more hydrophilic and prevents oxygen from contacting the QDs.
