Upconverting photons at the molecular scale with lanthanide complexes.

Although low, these values reflect a clear trend in adjusting the UC capabilities through structural modifications of the ligands. 47 As observed in the pioneering work of by Xiao and co-workers on Tm( iii ) and Nd( iii ) complexes with DPA and EDTA ( Fig. 2 ), these two metal ions are also capable of ESA UC. 38 So far, molecular ESA UC emission
