About the Journal :

Experimental and Theoretical NANOTECHNOLOGY (ETN) is a multidisciplinary peer-reviewed international journal published four issues a year. It includes specialized research papers, short communications, reviews and selected conference papers in special issues on the characterization, synthesis, processing, structure and properties of different principles and applications of NANOTECHNOLOGY; with focus on advantageous achievements and applications for the specialists in engineering, chemistry, physics and materials science.

ETN covers and publishes all aspects of fundamental and applied researches of experimental and theoretical nanoscale technology dealing with materials synthesis, processing, nanofabrication, nanoprobes, spectroscopy, properties, biological systems, nanostructures, nanoelectronics, nano-optics, nano-mechanics, nanodevices, nanobiotechnology, nanomedicine, nanotoxicology within the scope of the journal. ETN aims to acquire the recent and outstanding researches for the benefit of the human being.



PREPARATION, ANALYSIS AND CHARACTERIZATION OF ITO NANOSTRUCTURES

Conductive and highly transparent indium tin ox- ide (ITO) thin films were prepared on photosensitive glass substrates by the combination of sol–gel and spin-coating techniques.  First, the substrates were coated withamorphous Sn-doped indium hydroxide, and these amorphous films were then calcined at 550◦C to produce crystalline andelectricallyconductiveITOlayers.Theresultingthin films were characterized by means of scanning electronmicroscopy, UV-Vis spectroscopy, X-ray photoelectron spectroscopyandspectroscopicellipsometry.Themeasurements revealedthattheITOfilmswerecomposedofsphericalcrystallitesaround20nminsizewithmainlycubiccrystalstructure. The ITO films acted as antireflection coatingsincreasing the transparency of the coated substrates compared to that of the bare supports. The developed ITO films with a thickness of 170–330 nm was highly transparent in the visible spectrum with sheet resistances of 4.0–13.7 kQ/sq. By coating photosensitive glass with ITO films, our results openupnewperspectivesinmicro-andnano-technology, for example in fabricating conductive and highly transparent 3D microreactors.
