文摘

Addition of Tb³⁺ salts to a solution of a (YbL_D) complex in D₂O resulted in the formation of [(YbL_D)₂Tb_x] (x = 1 to 3) complexes that, upon NIR excitation at 980 nm, showed an unprecedented Yb to Tb upconversion sensitization phenomenon resulting in the observation of the typical green emission of Tb.
