1910 Encycl. Brit. X. 72/1 H. Kauffmann..suggested that the property [of fluorescence] is due to the presence of at least two groups. The first group, named the ‘luminophore’, is such that when excited by suitable aetherial vibrations [it] emits radiant energy; the other..acts with the luminophore in some way or other to cause the fluorescence.

1949 P. Pringsheim Fluorescence & Phosphorescence v. 392 The strong absorption of visible light which is characteristic of dyes was ascribed to the presence of certain unsaturated groups, such as the azo group  NN, the ethylene group HCCH, and the carbonyl group >CO, which were called chromophors. These chromophors were at first supposed also to be the carriers of fluorescence as ‘luminophors’.
