Preperation of Alq3 Thin Films for Organic ElectroLuminescence using plasma ablation method

Organic electroluminescence thin films were prepared by pulsed laser deposition method using high density Alq₃ (tris (8-hydroxyquinoline) aluminum) targets which produced by shock compaction technology. The experimental results suggest that Alq₃ thin films can be deposited at high fluence above 2.3J/cm². XPS results suggest that prepared Alq₃ films have Al 2p peak, and the spectrum have peak shift caused by oxidation. UV-Vis spectrum shows that the prepared films have absorption around 400 nm. The results suggest that PLD method maybe one of the effective method to prepare high quality Alq₃ films which work as organic electro-luminescence displays.
