The invention pertains to a light-emitting device comprising a light-emitting layer comprising a metal-organic donor-acceptor complex, characterized in that the metalorganic donor-acceptor complex has formula (1): (D-X)n-A' wherein D stands for donor and is independently chosen from an Ir(III), Zn(II), Cu(II), and Os(II)-ligand complex, the ligands being such that a blue/green emission spectrum is obtained; A' stands for acceptor and is a Ru(II), Ir(III), Os(II), Pd(II), Pt(II), Re(I), Cu(I) or lanthanide(III)-ligand complex, the structure and composition being chosen such that an orange/red emission is obtained; X is independently selected from a bond and an organic linker moiety, and n is 1 or 2, satisfied the above requirements, and n is 1 or 2.
