文摘

•: Relaxation of triplet excited states of [Ir(ppy)₂bpy]⁺ are studied using time-resolved spectroscopy.
•: Multiple phosphorescence bands are from ligand charge transfer and metal-to-ligand charge transfer states.
•: In DMF/AOT/hexane reverse micelle, the blue and green bands become intense to yield a broad emission.
•: The ³LC and green–blue ³MLCT bands are intense because of encapsulated in confined environment limiting the structural relaxation of the excited states.
