• Luminescence spectra and lifetimes are presented for the rare earth ions sensitized by [1]benzopyrano[3,4-<I>c</I>]pyridine-4,5(3<I>H</I>)-dione derivatives in dilute solutions. It is to be noted that, among the benzopyranopyridine derivatives investigated, 2-phenyl-[1]benzopyrano[3,4-<I>c</I>]pyridine-4,5(3<I>H</I>)-dione brings about the most efficient sensitization for the luminescence of europium and terbium ions. Some discussions are made of the energy-transfer processes from these excited benzopyranopyridine derivatives to terbium ions.
