title: Ratiometric luminescence thermometry based on crystal-field alternation at the extremely narrow ⁵D₀ → ⁷F₂ transition band of europium(III).
abstract: A dinuclear europium(III) complex with a structure of [BP-(Eu(III))2-(ODA)3] (BP = 2,2'-bipyridine-6,6'-dicarboxylic acid bis(N-hydroxy-succinimide) ester, ODA = diglycolic acid) shows a fully reversible emission spectral change at the extremely narrow (5)D0 → (7)F2 transition band in response to temperature changes ranging from 283 K to 333 K.
