Electroluminescence from a single layer of poly(n-vinylcarbazole)‎ doped with a new 1,2,4-triazole derivative

الملخص EN

We report light emission from a single layer thin film device.

This device is comprised of a hole transporting polymer, poly (N-vinylcarbazole) (PVK) doped with a new luminescent 1, 2, 4-triazole derivative sandwiched between an indium tin oxide electrode (ITO) and an aluminum electrode.

We have studied the current versus voltage (I-V) characteristics, the electroluminescence versus voltage (EL-V) characteristics, and the lifetime of the device.

Thinner samples revealed a lower EL threshold voltage VT compared with the conventional organic light emitting diodes (OLEDs) reported in the literature.

This VT increased with increasing the sample thickness.
