1.5 µm Luminescence from ErQ Based Organic Light Emitting Diodes

Abstract

Organic light emitting diodes have been fabricated using erbium tris(8-hydroxy-quinoline) as the emitting layer and N, N′-diphenyl-N, N′-bis(3-methylphenyl)-1, 1′-biphenyl-4, 4’-diamine (TPD) as the hole transporting layer. Room temperature electroluminescence was observed at 1.5 µm due to intra-atomic transitions between the4I13/2 and4I15/2 levels in the Er3+, ion. These results make the possibility of producing silicon compatible 1.5 µm technology based on such devices a reality.
