Abstract

The effects of nitrogen, oxygen, and moisture on the electron mobilities of tris(8-hydroxyquinoline) aluminum (Al q3) have been examined by time-of-flight (TOF) technique at room temperature under an applied electric-field range of 0.3-1 MVcm. Our results suggest that both oxygen and water molecules can impede electron conduction in Al q3. Detailed analysis suggests that water molecules induce electron traps even at very low dosages. Oxygen interacts with Al q3 at high dosages and results in highly dispersive TOF signals. Moisture appears to be more detrimental than oxygen in hindering electron transport in Al q3.
