Tris(8-hydroxyquinoline)aluminum (AlQ) powder has been characterized using photoluminescence and electron spin resonance (ESR). The broad asymmetric excitation band is centered at βΌ425 nm, while the emission band centered at βΌ505 nm is similar to those reported in films. A significant ESR signal wit
