Abstract

Single-layer blue light-emitting diodes (LEDs) are fabricated by spin coating a blend of 9,10-bis(3́,5́-diaryl)phenyl anthracene in poly(N-vinylcarbazolc) (PVK) or in the mixture of PVK and an electron-transporting molecule, 2-tert-butylphenyl-5-biphenyl-1,3,4-oxadiazole. The Commission Internationale de l'Eclairage coordinates of the resulting LEDs are very close to that of the blue standard from the National Television Standards Committee. These devices also show excellent color stability when operated at a voltage span from 6 to 22 V. High external quantum efficiency (>1.5%) and brightness (>3000 cd/m 2) can be obtained in these devices. © 2004 American Institute of Physics.
