Abstract

This letter reports that the 1.54 mu m electroluminescence efficiency of the organic light emitting diode (OLED) with a structure of nanometer. thick polycrystalline silicon (NTPS)/NPB/ErQ/AlQ/Al is two orders of magnitude higher than that of the OLED with a structure of thick crystalline silicon/NPB/ErQ/Al, which is similar to the OLED reported in literature [Curry et al., Appl. Phys. Lett. 77, 2271 (2000)]. Such an improvement is mainly attributed to the fact that hole injection is controlled by NTPS anode and holes are blocked by AlQ to match electron injection, and a higher light out coupling as well.
