  • 简介:氢存储的关键是与轻集体、大表面和富有的吸附地点设计新材料。在综合基于最近的试验性的成功tripyrrylmethane,我们探索了Ti-tripyrrylmethane基于的2D为氢存储使用的多孔的结构密度功能的理论。我们发现了结构是稳定的,并且暴露的Ti地点能与平均绑定绑三个氢分子0.175eV/H的精力在房间温度并且在周围的压力为氢的存储和版本躺在精力窗户的2,。

  • 简介:首次制备出粉末微晶BaCl0.5Br0.5F:Sm2+红色发光材料,并测量了其低温光谱。发现其谱线宽度与BaClF:Sm2+的相比较有了约十倍左右的非均匀增宽,而且相应于5D0,1,2→7F0,1的谱线由两个峰间距分别为15cm-1,65cm-1的谱线构成,峰间距只与基态7F0和7F1有关。W.Lenth&W.E.Morener[1]讨论了光子门光谱烧孔作为频率微区光学记录的理论和应用的可能性。对于长存的光谱烧孔,可以进行二进制的数据存储与改写。该技术为实现大容量、高速度的光学计算机的应用提供了新的前景。在这方面已经有了不少的研究工作[2~6]。为提高存储容量,需使光谱线非均匀增宽,以提供更多的光谱烧孔可能性。为此目的,首次制备出粉末微晶BaCl0.5Br0.5F:Sm2+红色发光材料,并测量了其低温光谱,并将其与BaClF:Sm2+的低温光谱进行了比较分析。
