Figure 4From: Quantum dots coordinated with conjugated organic ligands: new nanomaterials with novel photophysicsAbsorption curve for ∼4.5 nm CdSe quantum dots (solid curve) and oligo-(phenylene vinylene) (OPV) photoluminescence spectrum (dashed curve). The arrow denotes the wavelength location of the excitation laser (457 nm). The cutoff below 500 nm in the OPV photoluminescence is due to the choice of filtersBack to article page
