0Suitable medium for CsPbBr3 quantum dots toward light-emitting-diodes fabrication

To research optical properties of materials for light-emitting-diodes (LEDs) fabrication, CsPbBr3 quantum dots (QDs) were dispersed in five different substrates to investigate their luminescence. The results show that CsPbBr3 QDs embedded in glass matrices have superior stability, however, the QDs could not be evenly distributed in the matrices, which resulted in uneven luminescence of the glass. To solve this problem, epoxy resin was introduced as cladding material, which yielded a product that had good stability and consistency. CsPbBr3 QDs embedded in epoxy resin show great potential for green fluorescent components in LED applications. (C) 2018 Elsevier B.V. All rights reserved.
