Nguyen, Phuong Hoai Nam (2014) Enhanced Performance in Polymer Light Emitting Diode by using Ultra–Thin Conductive Films as the Buffer Layer. Communications in Physics, 24 (3S1). p. 101. ISSN 0868-3166

The ultra-thin nanocomposite films based on the nano-crystal TiO$_{2}$ (TiO$_{2}$-nc) or multi-walled carbon nano-tube (MWCNTs) were prepared and used as the buffer layers in the fabrication of the organic light-emitting diodes (OLEDs). The injection efficiency of the hole and electron was improved by inserting an ultra-thin buffer layer between the electrodes and emissive layer. The turn-on voltage of the device with the buffer layers was lowered from 4 to 2.5V, and the current density was increased from 0.3 to 0.7~mA/mm$^{2}$, in comparison with the device without such a buffer layer. These devices showed a high efficiency and good stability.
