Experimental and Theoretical NANOTECHNOLOGY

About the Journal :

Experimental and Theoretical NANOTECHNOLOGY (ETN) is a multidisciplinary peer-reviewed international journal published three 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.



STRUCTURAL AND OPTICAL PROPERTIES OF NANOPARTICULATE Y2O3:EU2O3

Nanoparticulate Y2 O3 :Eu2 O3 with a small, uni- form particle size and a well-defined composition was syn- thesized using a low temperature microwave plasma pro- cess. The structural evolution and the luminescence prop- erties were studied in different states of annealing and Eu2O3 addition using X-ray diffraction, transmission elec- tron microscopy, and UV-photoluminescence spectroscopy. As synthesized, the samples were amorphous and showed only weak luminescence. Subsequent annealing steps from 500°C to 800°C lead to the formation and growth of cu- bic Y2O3:Eu2O3 nanocrystals(5–20 nm) and a concomitant strong increase of the luminescence yield already at small grain sizes in the range of 10 nm. No self-quenching effects were observed up to 11 mol% Eu2O3 .
