title: White Light-Emitting Diodes with Excellent Color Rendering Based on Organically Capped CdSe Quantum Dots and Sr3 SiO5 :Ce(3+) ,Li(+) Phosphors.
abstract: White LEDs are fabricated through a combination of blue LEDs with Sr3 SiO5 :Ce(3+) ,Li(+) phosphors and organically capped CdSe quantum dots (QDs), which exhibit a 2D superlattice. The combination of blue emission from the LEDs, greenish-yellow emission from the phosphors, and red emission from the QDs generates white light. As-synthesized white LEDs show excellent color rendering properties and stable color coordinates against increasing forward bias currents.
