PHOSPHORESCENCE EMITTING SOLID, ORGANIC ELECTROLUMINESCENCE ELEMENT AND ORGANIC ELECTROLUMINESCENCE DEVICE

A phosphorescence emitting solid comprising an organometallic complex which has a tridentate ligand coordinating to a central metal through two nitrogen atoms and one carbon atom positioning between said two nitrogen atoms and binding with said two nitrogen atoms via bonds and has a halogen atom as a ligand; a luminescent element using the solid; and an organic EL device using the element. The phosphorescence emitting solid can emit a phosphorescence having very high intensity in a solid state, and thus, the use of the solid in an organic EL element allows the significant improvement of the luminous efficiency, which results in the reduction of electric power consumption in an organic EL device.
