1.5-μm light-emitting diodes which operate at room temperature have been fabricated on silicon substrates. The devices use an erbium-containing organic light-emitting diode (OLED) structure which utilizes p++ silicon as the hole injection contact. The OLEDs use N, N′-diphenyl-N,N′-bis(3-methyl)-1,1′-biphenyl-4,4′- diamine as the hole transporting layer and erbium tris(8-hydroxyquinoline) as the electron conducting and emitting layer. © 2000 American Institute of Physics.
