We demonstrate hybrid white light emitters by employing Gallium Nitride (GaN)-based light-emitting diodes (LEDs) as blue emitters and aggregation-induced emission (AIE) organic molecule 4,7-Bis[4-(1,2,2-triphenylvinyl)phenyl]benzo-2,1,3-thiadiazole (BTPETD) as down-converted yellow emitters. The fabricated device shows CIE coordinates of (0.32, 0.33) and 45.4% optical extraction efficiency from BTPETD layer with pump leakage of 17.3%. At driving current of 30 mA, the highest luminous efficacy of 123.8 lm/W was obtained for the hybrid devices which corresponded a luminance of 1.4 × 105 cd/m2. Our work indicates that formation of aggregates from AIE materials such as BTPETD is able to greatly enhance the device extraction efficiency and improve the hybrid white LED performance.
