Abstract
A white-light-emitting diode (white LED) with good color rendering index is fabricated based on a blue LED combined with high-fluorescence CdS:Cu/ZnS quantum dots (QDs) and YAG:Ce phosphors. The reabsorption problem is overcome by the excellent optical properties and enlarged Stokes shift of the QDs with low absorption of light of wavelengths longer than 470 nm.
