Abstract
Nickel compounds nanoparticles have great potential for optoelectronic devices. In this study, we investigate the structural, morphological, optical, and electrical properties of (PET/ITO/NiO/Ag) and (PET/ITO/β-Ni(OH)2/Ag) heterojunction obtained by chemical bath deposition and spin coating, which are low-cost techniques. The crystal size was obtained by XRD diffraction; the structural analysis showed crystal dimensions in the 2–7 nm intervals. An enhanced conductivity of 0.86 (Ω/cm) and an increment in the lifetime carriers compared with samples without annealing treatment were observed. The I–V characteristics measured at room temperature, the height of the Schottky barriers, were estimated in the range of 0.56–0.60 eV. This method leads to an affordable application in optoelectronic devices.
期刊介绍：
Optical Materials has an open access mirror journal Optical Materials: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review.
The purpose of Optical Materials is to provide a means of communication and technology transfer between researchers who are interested in materials for potential device applications. The journal publishes original papers and review articles on the design, synthesis, characterisation and applications of optical materials.
OPTICAL MATERIALS focuses on:
• Optical Properties of Material Systems;
• The Materials Aspects of Optical Phenomena;
• The Materials Aspects of Devices and Applications.
Authors can submit separate research elements describing their data to Data in Brief and methods to Methods X.
