Abstract
The invention relates to lighting emitting devices and systems comprising a luminescent composition, said luminescent composition comprising: (i) a first emitting material, said first emitting material having a host lattice doped with EUions; (ii) a second emitting material, said second emitting material having a host lattice doped with Tbions; and (iii) sensitizer material, which sensitizer material is excitable in the violet-to-blue (400 to 480 nm) wavelength range and has an emission spectrum which overlaps at least partly with one or more excitation bands of the first emitting material and with which overlaps at least partly with one or more excitation bands of the second emitting material.
