Efficient and chromaticity stable green and white organic light-emitting devices with organic–inorganic hybrid materials

Abstract

Efficient inverted bottom emissive organic light emitting diodes (IBOLEDs) with tin dioxide and/or Cd-doped SnO2 nanoparticles as an electron injection layer at the indium tin oxide cathode:electron transport layer interface have been fabricated.

“…As such, the huge energy barrier gap between the cathode ITO and the electron 4 transport layer (ETL) is the main reason hindering the excellent performance of IOLEDs. Some researchers have proposed some approaches to realizing the efficient electron injection capability of IOLEDs as follows: (i) A variety of materials such as low-WF zinc oxide, tin dioxide, and ultra-thin Alq3-LiF-Al trilayer, can be used as an electron injection layer (EIL) [16][17][18]; (ii) The ultra-thin Al and metal sulphide can be used to modify the cathode ITO of IOLEDs, thus reducing the electron injection barrier to improve the photoelectric performance and enhance the stability of IOLEDs [19][20][21];…”

“…Specifically, Gaussian peak E H and their standard deviations σ H can be determined by observing the width of the HOMO derived feature measured by UPS. In addition, the work function of ITO (4.8 eV) 52 was adopted in the iterative electrostatic model as Wf elec . The IE position was obtained from the intersection of the tangent with the baseline.…”
