Luminous efficiency improvement of polymer light-emitting diodes with platinum nanolayer at the PEDOT:PSS-ITO
Abstract:
A platinum (Pt) nanolayer was successfully deposited on indium titanium oxide (ITO) as a buffer layer for polymer light-emitting diodes (PLEDs) using a rapid and low-cost sputtering system at room temperature. With a 5 s Pt-dispersed ITO as the anode window substrate of the PLED, a maximum current efficiency of 4.00 cd/A was realized, which is notably higher than that of a typical PLED (1.13 cd/A). It was determined that the average current efficiency and electroluminescence intensity of the proposed PLED were enhanced by 2.5 times and 290%, respectively, compared to a typical PLED.
