Paper Abstract

We have demonstrated that it is possible to product organic light emitting diodes containing lanthanide ions which provide sharp electroluminescence emission at a range of wavelengths in the near infrared including 0.9 micrometers , 0.98 micrometers , 1.064 micrometers , 1.3 micrometers and 1.5 micrometers . For devices grown on ITO substrates we have demonstrated bright electroluminescence at drive voltages of approximately 12 V. We have shown that these diodes can be integrated onto silicon substrates and use the silicon as the anode of the device. For erbium based devices which emit at a wavelength of 1.5 micrometers we have demonstrated devices with room temperature internal efficiencies of approximately 0.01% at a drive voltage of 33 V.
