By a News Reporter-Staff News Editor at Journal of Technology -- Research findings on Non-Crystalline Solids are discussed in a new report. According to news reporting from Beijing, People's Republic of China, by VerticalNews journalists, research stated, "Tm3+/Yb3+ co-doped La2O3-TiO2-ZrO2 glass-ceramics with intense blue emission have been fabricated by containerless processing in an aerodynamic levitation furnace, following by heat treatment at different temperatures in the air. The intensity of blue upconversion luminescence increases two times compared with the precursor glass after a heat treatment process at 890 degrees C. Blue and red emissions centered at 476 nm and 650 nm owing to the Tm3+ transitions (1)G(4) ? H-3(6) and (1)G(4) ? F-3(4) are achieved under the excitation of 980 nm at room temperature."
The news correspondents obtained a quote from the research from the Chinese Academy of Sciences, "The upconversion luminescence is based on a two-photon process by the cooperative sensitization which transfers energy from Yb3+ to Tm3+. Furthermore, Tm3+ and Yb3+ ions are enriched in nanoparticles which disperse in glass matrixes. Dense lattice fields and strong partitions of nanocrystals reduce energy losses caused by mutual interactions among rare earth ions to obtain strong upconversion luminescence."
According to the news reporters, the research concluded: "The presented intense blue emission of Tm3+/Yb3+ co-doped La2O3-TiO2-ZrO2 glass-ceramics shows potential promising perspective in the optical materials."
