Efficiency Enhancement in Polymer Light-Emitting Diodes via Embedded Indium–Tin–Oxide Nanorods

Abstract

Indium-tin-oxide (ITO) nanorods were fabricated in 10 min from commercially available ITO substrate using wet chemical etching method. The optical properties of the ITO nanorods were investigated using transmission spectroscopy and dark-field optical microscopy. The transmittance and light-scattering characteristics of the ITO nanorods were better than those of ITO film. The ITO nanorod layer was further used as a transparent anode in polymer light-emitting diodes (PLEDs). The brightness and current efficiency of the PLED with the ITO nanorod layer were enhanced. This performance enhancement can be attributed to the excellent optical and electrical properties of the ITO nanorod layer.

Enhancing the Water Stability of Al‐MIL‐101‐NH2 via Postsynthetic Modification

“…In OPVs, the introduction of geometrical light trapping using transparent electrodes, hole‐injection layers, and active layers has been demonstrated 15–25. Furthermore, in the field of light‐emitting diodes, nanostructures are conventionally used for better light extraction 26–28. Textured electrodes can provide efficient light trapping to increase the optical path and to enhance solar‐cell efficiency.…”

Influence of Substrate Orientation and Oxygen Partial Pressure on the Morphology, Structure, and Electrical Property of Epitaxial Indium Tin Oxide Films

“…The indium tin oxide (ITO) is one of the most important and commonly used transparent conducting oxides. Because of the high transparency in the visible region and excellent electrical conductivity, ITO films have been widely employed in various research fields such as biosensing technology, , electroanalysis, liquid crystal displays, , photovoltaic devices, , and light-emitting diodes. − In addition to this, ITO films with flat surfaces could be used as conductive substrates for specific characterization techniques such as ultraviolet photoelectron spectroscopy and scanning tunneling microscopy . Various techniques are available for ITO film preparation, including sol–gel process, spray pyrolysis, vacuum evaporation, , electron beam evaporation, magnetron sputtering, − pulsed laser deposition, − ion beam sputtering, chemical vapor deposition, − atomic layer deposition, and so forth.…”

Light extraction from quantum dot light emitting diodes by multiscale nanostructures

“…17 Nevertheless, the commonly reported nanostructures limit the further development of high-performance QLEDs due to their inherent drawbacks such as incomplete reection suppression, high haze, angular dependence, and image blurring. 18,19 When comparing the performance of QLEDs and OLEDs, the most signicant difference is that QLEDs have symmetric and Gaussian-like emission spectra with a full width half maximum (FWHM) typically as narrow as 30 nm, while for OLEDs the spectrum is usually broader ($100 nm) and more asymmetric. 20 The narrower emission spectra of QLEDs require more delicately designed nanostructures to further improve the EQE and match the performance of OLEDs.…”
