摘要：

Two well known electroluminescent (EL) compounds, aluminum and zinc metallo-8-hydroxyquinolates have been synthesized. Their chemical and physical properties like NMR, FTIR, Cyclic Voltammetry, absorption and EL are studied. Organic LEDs are fabricated using both the material as emissive layers. Electroluminescence spectra of the complexes are measured. Alq(3) and Znq(2) give peak emission in yellow-green region at wavelengths 527nm and 540nm respectively. Znq(2) is slightly red shifted compared to Alq(3) because metal to ligand charge transfer is more in Znq(2). A study of ON voltage, luminance efficiency and stability of OLEDs using both materials is made.
