Abstract

Dye-bridged nanohybrids in which red and green luminescent dyes are covalently bridged to oligosi-loxane for white light-emitting diodes (LEDs) are reported on page 5767 by Byeong-Soo Bae and co-workers. The nanohybrid-based white LEDs have a high color rendering index and high thermal resistance due to the siloxane network and the chemically bridged hybrid structure. This organic luminescent material is a potential alternative to inorganic phosphors for high-performance white LEDs.
