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

摘要

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.
