REVIEW ON METALLIC OXIDE NANOPARTICLES AND THEIR APPLICATION IN OPTOELECTRONIC DEVICES

Abstract

Among the large family of metallic oxides, there is a considerable group possessing excellent semiconducting
properties. What follows, they are promising materials for applications in the field of optoelectronics and
photonics. Thanks to the development of nanotechnology in the last few decades, it is now possible to
manufacture a great variety of different nanostructures. By controlling their size, shape, composition and
crystallinity, one can influence such properties as band gap, absorption properties, surface to volume ratio,
conductivity, and, as a consequence, tune the material for the chosen application. The following article reviews
the research conducted in the field of application of the metallic oxide nanoparticles, especially ZnO, TiO2 and
ITO (Indium-Tin Oxide), in such branches of optoelectronics as solid-state lightning, photodetectors, solar-cells
and transparent conducting layers.
