Tailoring hole injection using facilely solution-processed economical calcium carbonate in near ultraviolet organic light-emitting diodes
Economical nano-scale CaCO3 particles with superior aqueous dispersion and facile preparation process of sand milling are demonstrated. The spin-coated CaCO3, poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) and CaCO3-doped PEDOT:PSS films are characterized with scanning electron microscope, atomic force microscope, X-ray/ultraviolet photoelectron spectroscopy, current–voltage characteristics and impedance spectroscopy analysis, confirming good surface morphology and satisfactory hole injection properties. With CaCO3-doped PEDOT:PSS tailoring hole injection and 2-(4-biphenyl)-5-(4-tert-butylphenyl)-1,3,4-oxadiazole as emitter, efficient near ultraviolet organic light-emitting diodes have been constructed. The device gives maximum external quantum efficiency of 1.16%, radiance of 1.95 mW/cm2, and stable electroluminescent spectra peaking at 395–404 nm.
期刊介绍：
The Journal of Materials Science: Materials in Electronics is an established refereed companion to the Journal of Materials Science. It publishes papers on materials and their applications in modern electronics, covering the ground between fundamental science, such as semiconductor physics, and work concerned specifically with applications. It explores the growth and preparation of new materials, as well as their processing, fabrication, bonding and encapsulation, together with the reliability, failure analysis, quality assurance and characterization related to the whole range of applications in electronics. The Journal presents papers in newly developing fields such as low dimensional structures and devices, optoelectronics including III-V compounds, glasses and linear/non-linear crystal materials and lasers, high Tc superconductors, conducting polymers, thick film materials and new contact technologies, as well as the established electronics device and circuit materials.
