Abstract: It is an object of the present invention to provide a light-emitting material with high light emission intensity. It is another object to provide a light-emitting element with high light emission efficiency. Moreover, it is another object to provide a light-emitting device and an electronic appliance with reduced power consumption. A light-emitting material contains at least a light-emitting substance, a base material, and an additive which is an element belonging to group 14 of the periodic table or a compound containing two or more kinds of elements belonging to group 14, or a compound containing at least two or more kinds of elements each belonging to a different group chosen from group 13, group 14, and group 15. Due to the light-emitting material, a light-emitting element and an electronic appliance which has high light emission efficiency and can be driven at a low voltage can be obtained.
