Tóm tắt

The phosphorescent organometallic complexes of iridium (III) (Ir-I) and platinum (II) (Pt-I) were prepared using 2-phenyl pyridine and acetyl acetone as ligands and their photophysical properties were characterized. The Ir-I complex gave the green photoluminescence (APL = 519 nm) and Pt-I complex exhibited a little blue shift in photoluminescence (APL = 484 nm) due to the appearance of metal center transitions (d - d*). In both cases, their lifetime was rather long. The two obtained complexes were further used for the fabrication of simple polymer light emitting diodes (PLEDs) using PVCz as a host polymer. These devices have emitted green electro luminescence corresponding to the maximum photoluminescence of each complex and their maximum brightness was observed at high voltage.
