Abstract

We have investigated Electrical Properties of Organic Light-Emitting Diode depending on Varied Temperature using 8-hydroxyquinoline aluminum($Alq_3$) as an electron transport and emissive material. We analyzed the electrical properties of organic light emitting diodes by impedance characteristics of ITO/$Alq_3$/Al. Impedance characteristics was measured complex impedance Z and phase e in the frequency range of 40 Hz to $10^7\;Hz$. From these analyses, we are able to interpret electrical Properties of OLED depending on temperature.
