Abstract

This study refers to a new organometallic compound in which the primary atom (La) has a fused ring structure containing thiophene groups, an organic light-emitting diode, and an organic light-emitting diode. The organometallic compound acts as a dopant for the phosphorescent layer of the organic light-emitting diode. Therefore, the operating voltage of the diode is lowered, and its light-emitting efficiency and device lifespan are improved.
