Abstract
Schiff base copper complex for OLEDs application was synthesized and ligand was characterized by NMR, mass spectroscopy, FTIR, and powder XRD. Photo-physical properties were recorded on UV-visible and photoluminescence spectroscopy. Their phosphorescent emissive-layer in green light emitting multi-layered OLED device was investigated. It exhibits CIE chromaticity color coordinates at x = 0.377 and y = 0.583. The maximum brightness, current efficiency and power efficiency for the 3.0 weight% Cu(II) complex doped electroluminescent device are 6436 cd/m2, 15.4 cd/A and 6.7 lm/W, respectively. These results opens the route for the development of cost-effective metal complex for Opto-electronic applications as a part of strong electroluminescent materials.
