N2 - As electroluminescent material zinc bis (2-phenyl-8-hydroxyquinolato) [Zn (Q-Ph)2] was synthesized and characterized by H NMR, UV-Vis and MS measurements. DCJTB [4-(dicyanomethylene)-2-t-butyl-6 (1, 1, 7, 7-tetramethyljulolidyl-9-enyl)-4H-pyran], a highly efficient fluorescent dye, and Zn (Q-Ph)2 were used to fabricate a kind of novel non-doping organic light-emitting diode with a structure of ITO/NPB {N, N′-Di [(1-naphthalenyl)-N, N′-diphenyl]-(1, 1′-biphenyl)-4, 4′-diamine}/DCJTB/Zn (Q-Ph)2/AlQ3 (8-hydroxyquinoline aluminum)/Al. By changing the thickness of ultra-thin layer DCJTB, yellow-light, red-light and orange-light emission from OLEDs were studied. Their luminescent color, electroluminescent mechanism and recombination zone were optimized in this paper. When a 0.5 nm-thick DCJTB was used, a stable red emission was obtained. With a lower turn-on voltage at about 5.5 V, the non-doping OLED showed a maximum brightness of 420 cd/m2 and current density of 250 mA/cm2 at 25 V.
