Quantum Dot/J-Aggregate Blended Films for Light Harvesting and Energy Transfer

摘要: This paper describes the solution preparation of thin films composed quantum dots and thiacyanine J-aggregates, making use size tunable emission narrow, intense absorption J-aggregates in solid state. These blended exhibit 90% energy transfer efficiency from to can uniformly cover a large area. Because presence enhances QD photoluminescence intensity by 2.5-fold over QDs alone, these state materials may be useful downconversion applications or fundamental investigations light harvesting.
