| 1 | Effect of gadolinium incorporation on optical characteristics of YNbO_4:Eu^(3+) phosphors for lamp applications显示文摘Eu3+-doped (Y,Gd)NbO4 phosphor was synthesized by solid-state reaction for possible application in cold cathode fluorescent lamps. A broad absorption band with peak maximum at 272 nm was observed which was due to the charge transfer between Eu3+ ions and neighboring oxygen anions. A deep red emission at the peak wavelength of 612 nm was observed which could be attributed to the 5D0→7F2 transition in Eu3+ ions. The highest luminance for Y1-x-yGdyNbO4:Eux3+ under 254 nm excitation was achieved at Eu3+ concentration of 18 mol.% (x=0.18) and Gd3+ concentration of 8.2 mol.% (y=0.082). The luminance of Y0.738Gd0.082NbO4:Eu3+0.18 was higher than that of a typical commercial phosphor Y2O3:Eu3+ and the CIE chromaticity coordinate was (0.6490, 0.3506), which was deeper than that of Y2O3:Eu3+. The particle size of the synthesized phosphors was controlled by the NaCl flux and particle size as high as 8 μm with uniform size distribution of particles was obtained. | Sung Hwan Choi G.

| 2 | Nature:研究利用单细胞分析阐明癌症干细胞在脑癌中的关键角色显示文摘近日。来自麻省总医院、博德研究所及哈佛大学的研究人员通过联合研究,在单细胞水平上对脑瘤基因组进行了分析。他们发现。癌症干细胞或许能够诱发少突神经胶质瘤的发生,少突神经胶质瘤是一种缓慢发展但却非常难以治愈的脑癌,相关研究刊登于Nature杂志上。同时研究者还首次在人类脑瘤样本中鉴别出了癌症干细胞及其分化的后代细胞。 | Itay Tirosh, Andrew S.
