Findings from University of Lorraine in the Area of Silicon Described

June 13, 2014



By a News Reporter-Staff News Editor at Science Letter -- New research on Silicon is the subject of a report. According to news reporting originating in Vandoeuvre les Nancy, France, by NewsRx journalists, research stated, "Neodymium-doped silicon-rich silicon oxide thin films SiOx:Nd (1

The news reporters obtained a quote from the research from the University of Lorraine, "Photoluminescence (PL) properties of the SiOx:Nd thin films were studied as a function of the silicon excess, the annealing temperature and the Nd content. For annealed samples, Nd-related PL peaks at 920 nm, 1100 nm and 1400 nm are observed. It is shown that, despite the efficient energy transfer between Si-nc and Nd3+ ions, the highest luminescence intensity is obtained for samples containing aSi-np. Moreover, the concentration quenching effect occurs for higher concentration values in samples containing aSi-op, compared to that containing Si-nc."

According to the news reporters, the research concluded: "These results show that Si-nc are not necessary to indirectly excite Nd3+ ions and that samples annealed at temperatures lower than 800 degrees C are of potential interest for applications because of a lower thermal budget compared to that required for samples containing Si-nc."
