Addition of lanthanide ions to dendrimer solutions showed that (a) the absorption spectrum of the dendrimer is almost unaffected, (b) the fluorescence of the dansyl units is quenched (c) the quenching effect is very large for Nd3+ (Fig. 7) and Eu3+, moderate for Er3+ and Yb3+, small for Tb3+, and very small for Gd3+ (d) in the case of Nd3+ (Fig. 7), Er3+, and Yb3+ quenching of the dansyl fluorescence is accompanied by the sensitized near-infrared emission of the lanthanide ion [42].

Gudel and coworkers have reported during recent years many cases of (near) infrared emission from several transition-metal ions. This was only possible by the use of suitable detectors of radiation (e.g. a cooled germanium photo-detector) and careful crystal synthesis. Here we mention some examples.
