New Findings from Korea Research Institute of Standards and Science in Nanocrystals Provides New Insights

May 23, 2014

By a News Reporter-Staff News Editor at Science Letter -- Investigators publish new report on Nanocrystals. According to news reporting out of Taejon, South Korea, by NewsRx editors, research stated, "Zinc lead oxide (Zn2PbO4) nanopowders were synthesized by a simple co-precipitation method using zinc nitrate and lead nitrate precursors in 2:1 proportion by carefully controlling the preparative parameters. Ammonium hydroxide was used to precipitate Zn2+ and Pb4+ cations simultaneously."

Our news journalists obtained a quote from the research from the Korea Research Institute of Standards and Science, "X-ray diffraction study of prepared samples indicates both orthorhombic and tetragonal phase formation of Zn2PbO4. The microstructural features are examined by scanning electron microscopy. Frequency dependent dielectric constant (epsilon') shows the usual dispersion behavior, while linear variation of AC conductivity (sigma(AC)) with frequency confirms the conduction due to small polaron. The DC resistivity decreases with increase in temperature indicating semiconducting behavior of samples."

According to the news editors, the research concluded: "To understand the conduction mechanism, complex impedance measurements are carried out."
