Description

Synthesis and photophysical properties of nonanuclear lanthanide(III) clusters, H10[Ln9(hesa)16(μ-O)10(NO3)] (hesa=hexylsalicylate, Ln=Gd, Tb and Yb) were investigated. By the ligand excitation at 380 nm in methanol, the Tb cluster exhibited luminescence due to the 4f-4f transitions of Tb(III) around 487, 549, 580, 621, 646, 670, and 680 nm (5D4→7F i : i=6, 5, 4, 3, 2, 1, 0). The Yb cluster also showed the photosensitized luminescence at around 980 nm (2F7/2→2F5/2). Especially, the Tb cluster gave a high emission quantum yield (Φ s>0.90) in methanol
