Abstract: Using transition anic chromophores with strong charge-transfer transitions as sensitizers for
efficient lanthanide luminescence is a new approach developed during the past decade. This review article
outlines briefly the relative electronic properties of lanthanide ions and the simplified energy transfer modes
anic ligands and lanthanide ions, and introduces systematically the approaches for efficient sensitized
(near-infrared, NIR) lanthanide luminescence, and highlights the advances to achieve lanthanide luminescence
through d-f energy transfer together with the applications in various fields. Particularly, recent progresses in our
group are summarized concerning the designed syntheses of a series of d-f plexes with
bifunctional acetylides as the bridging ligands for achieving lanthanide 髥 luminescence. Finally, the hot topics
and the research trends on lanthani
