Recent Findings from Ningbo University Has Provided New Information about Materials Science (Annealing time dependent 1.53 mu m fluorescence enhancement in Er3+-doped tellurite glasses containing silver NPs)

By a News Reporter-Staff News Editor at Journal of Technology -- Current study results on Materials Science have been published. According to news originating from Zhejiang, People's Republic of China, by VerticalNews correspondents, research stated, "Silver nanoparticles (NPs) were introduced into the Er3+-doped tellurite glasses (TeO2-Bi2O3-TiO2) and their effects on the 1.53 mu m band fluorescence of Er3+ and thermal stability of glass host were investigated."

Our news journalists obtained a quote from the research from Ningbo University, "It was found that the presence of silver NPs nucleated and grown during the heat annealing process, could improve the thermal stability and the 1.53 pm band fluorescence. Maximum enhancement in the 1.53 mu m band fluorescence was obtained in sample heat-treated for 48 h. However, further increase in the heat annealing time (similar to 72 h) reduces the fluorescence intensity."

According to the news editors, the research concluded: "Enhancement in the 1.53 mu m band fluorescence is attributed to the increased local electric field induced by silver NPs whereas the quenching is ascribed to the energy transfer from Er3+ ions to silver NPs."
