Abstract
Provided are a metal complex, an electroluminescent device containing the same, and a use thereof. The metal complex has a structure of M(L)(L)and can more effectively fine-tune a light-emitting color and adjust an emission peak width, thereby narrowing a full width at half maximum, making the light-emitting color more saturated, and improving device efficiency, current efficiency, and external quantum efficiency.
