A new electroluminescent material, salicylaldehyde anil zinc (SAZ) was synthesized, which can form high quality, thermal stability, nano-scale amorphous films by vacuum evaporation. Its structure, thermal stability were characterized by infrared (IR) spectra, differential thermal analysis-thermogravimetry (DTA-TG) analysis, respectively. The optical properties of SAZ were investigated by UV absorption spectra, Photoluminescence (PL) excitation and emission spectra. The highest occupied molecular orbits (HOMO), lowest unoccupied molecular orbits (LUMO) and optical band gap were evaluated by cyclic voltammetry curve and optical absorption band edge. The electroluminescent devices using SAZ as the emissive layer emit green light with a peak wavelength at 509 nm and a brightness of about 3.1 cd/m^2. 展开更多
