Studies Conducted at University of Milan on Nanoparticles Recently Reported

February 28, 2014

By a News Reporter-Staff News Editor at Science Letter -- Current study results on Nanoparticles have been published. According to news reporting originating from Milan, Italy, by NewsRx correspondents, research stated, "Ordered mesoporous silica nanoparticles (MSNs) were impregnated with different loadings of the luminescent complex tris(dibenzoylmethane) mono(1,10-phenanthroline)europium(III) (Eu(dbm)(3)phen), with the aim of increasing the luminescence by avoiding concentration quenching and having mainly in mind the application as spectral converter for multi-crystalline silicon solar cells. The morphological, structural and luminescence properties of the impregnated silica nanoparticles were characterized by N-2 physisorption, X-ray diffraction, transmission electron microscopy, infrared spectroscopy, UV-visible spectroscopy and photoluminescence excitation and emission measurements."

Our news editors obtained a quote from the research from the University of Milan, "Photostability was tested under 1 sun (1000 W/m(2)) illumination for 24 h and the related effects were inspected by UV-visible and photoluminescence spectroscopies. Impregnation of the complex into 50-70 nm MSNs with pore size tailored around 2.9 nm depressed concentration quenching and allowed the use of complex loadings as high as 23 wt%."

According to the news editors, the research concluded: "Sunlight irradiation caused a marked increase in the luminescence intensity."
