Study Data from R. Balderas-Xicohtencatl et al Provide New Insights into Nanoparticles

February 28, 2014



By a News Reporter-Staff News Editor at Science Letter -- A new study on Nanoparticles is now available. According to news reporting from Oaxaca, Mexico, by NewsRx journalists, research stated, "The luminescent characteristics of Dy3+-doped Y2O3 nanopowders synthesized using the polyol method are reported. The Y2O3 nanoparticles presented a cubic phase crystalline structure of Y2O3 after an annealing treatment in oxygen ambient at temperatures above 600 degrees C. The averaged crystallite size determined from the X-ray diffraction peaks width was in the 20-32 nm range depending on the annealing temperature."

The news correspondents obtained a quote from the research, "Scanning and transmission electron microscopy studies indicate the formation of nanoparticle aggregates up to 175 nm in diameter. Photoluminescence and cathodoluminescence measurements show a predominant emission at 573 nm, which is attributed to the F-4(9/2) ? H-6(13/2) of the Dy3+ ion."

According to the news reporters, the research concluded: "The luminescence emission dependence with the dopant concentration and post-annealing temperatures is discussed."
