The objectives of this invention are to provide a novel Nile Red luminescent compound capable of emitting a light of which color is nearly crimson, a novel process for producing the same and a luminescent compound capable of emitting at a high luminance a nearly crimson light. This invention relates to a Nile Red luminescent compound emitting red light made by changing C═O in a Nile Red compound to C═CH—Ar, wherein Ar is an aromatic group including fluorine atoms, and by introducing an electron attractive aromatic acetonitrile into the skeleton of the Nile Red compound; a novel process for producing the Nile Red luminescent compound that comprises reacting a Nile Red pigment with an electron attractive aromatic acetonitrile, and a luminescent compound comprising a composition that includes the Nile Red luminescent compound.
