Eu(III) selective excitation spectroscopy involving the /sup 7/F/sub 0/ to /sup 5/D/sub 0/ transition has been briefly characterized as an important luminescence technique for metal binding sites. An experimental system consisting of a nitrogen laser and a tunable dye laser has been modified for measurements of the Eu(III) excitation spectra. The experimental setup gives the possibility for concurrent registration of excitation spectra and luminescence decay curves for every wavelength of excitation. The system is controlled by a PC using a specially written program for collecting and processing the /sup 7/F/sub 0/ to /sup 5/D/sub 0/ spectra of Eu(III).
