    Abstract This paper reports the spectroscopic behavior, thermal stability and temperature sensitivity of Ca2SiO4: Eu3+ phosphors. A series of Ca2SiO4: Eu3+ phosphors were synthesized by using an efficient combustion method. The X-ray diffraction (XRD) results showed that the prepared phosphors consist of a single phase orthorhombic structure. The field emission scanning electron microscope (FESEM)
    摘要 本文报道了Ca2SiO4:Eu3+ 荧光粉的光谱行为、热稳定性和温度敏感性。采用高效燃烧法合成了一系列Ca2SiO4:Eu3+荧光粉。X射线衍射(XRD)结果表明制备的荧光粉由单相正交结构组成。场发射扫描电子显微镜(FESEM)结果显示颗粒不规则和团聚。在激发波长 255 nm 下,PL 发射在波长 574、594、612、656 和 707 nm 处显示出五个峰,对应于跃迁 5D0→7F0、5D0→7F1、5D0→7F2、5D0→7F3 和 5D0→7F4分别。浓度猝灭现象归因于偶极-偶极相互作用。使用 Judd-Ofelt 理论估计不同 J 水平的强度和光谱参数。
  • Synthesis, Characterization and Photocatalytic Activity of β-Ca2-xZnxSiO4 (x = 0, 0.01 and 0.025)

    The compound of β-Ca2SiO4 has been considered as one of the important portand cement components. The existence of metals in the cement raw materials causes β-Ca2-xMxSiO4 formation possibility. The β-Ca2-xZnxSiO4 (x = 0, 0.01 and 0.025) has been prepared and characterized, and aplied for degradation of Congo red. The samples were synthesized by heating stoichiometric amounts of Zn(NO3)2·6H2O, CaCO3 and SiO2 at 950 ºC for 4 h followed by air quenching. The samples were characterized by using XRD, SEM, EDA and UV-visible spectroscopic methods. The XRD patterns indicate that the samples are isomorphous with β-Ca2SiO4. The SEM micrographs depicted the aggregated irregular shape particles having size about 0.2 μm. The EDA measurements revealed that the bulk compositions of materials are as expected. The doping of zinc increases the Eg of the sample and decreases the photocatalytic power for degradation of Congo red under sunlight.
    β-Ca2SiO4化合物一直被认为是重要的港口水泥成分之一。水泥原料中金属的存在导致了形成 β-Ca2-xMxSiO4 的可能性。我们制备了β-Ca2-xZnxSiO4(x = 0、0.01 和 0.025),并将其用于刚果红的降解。这些样品是通过在 950 ºC 下将等量的 Zn(NO3)2-6H2O、CaCO3 和 SiO2 加热 4 小时,然后在空气中淬火合成的。样品采用 XRD、SEM、EDA 和紫外可见光谱法进行表征。XRD 图谱表明,样品与 β-Ca2SiO4 为同构体。扫描电镜显微照片显示出聚集的不规则颗粒,大小约为 0.2 μm。EDA 测量显示,材料的主体成分符合预期。锌的掺杂增加了样品的 Eg 值,降低了在阳光下降解刚果红的光催化能力。
  • Coated/treated metal silicate absorbent particles
    申请人:Withiam C. Michael
    公开号:US20060171972A1
    公开(公告)日:2006-08-03
    Coated particles of metal (such as calcium) silicate that exhibit excellent odor neutralization and sebum absorption properties when present within certain cosmetic and/or personal care formulations and suspensions are provided. Uncoated calcium silicate exhibits a high pH level that may have a deleterious effect upon such cosmetic and/or personal care compositions, thereby rendering the overall composition ineffective for its intended purpose, particularly if the calcium silicate is present in its usual state at high loading levels. Alternatively, if certain materials present within personal care compositions exhibit a sufficiently low pH level, the effectiveness of such calcium silicates may be compromised as well. Such novel coated/treated calcium silicates thus permit high loadings of this beneficial odor neutralizing/sebum absorbing additive within cosmetic and/or personal care formulations without causing any appreciable instability issues or viscosity modification concerns or allow for coexistence with such low pH materials without any appreciable reduction in performance capabilities of the calcium silicates themselves. Certain personal care compositions comprising these novel coated calcium silicate particulates are encompassed within this invention as well.
    本发明提供了金属(如钙)硅酸盐的涂层颗粒,当存在于某些化妆品和/或个人护理配方和悬浮液中时,表现出优异的气味中和和皮脂吸收性能。未涂层的硅酸钙表现出高pH值,可能对这些化妆品和/或个人护理组合物产生有害影响,从而使整个组合物对其预期用途无效,特别是如果硅酸钙以高负荷水平存在于其通常状态下。或者,如果个人护理配方中存在某些材料表现出足够低的pH值,这些硅酸钙的有效性也可能受到损害。因此,这种新型涂层/处理的硅酸钙允许高负荷这种有益的气味中和/皮脂吸收添加剂存在于化妆品和/或个人护理配方中,而不会引起任何明显的不稳定性问题或黏度修改问题,或者允许与这些低pH材料共存,而不会对硅酸钙本身的性能产生任何明显的降低。本发明还包括某些包含这些新型涂层硅酸钙颗粒的个人护理配方。

    本发明提供了一种金属(如钙)硅酸盐的涂覆颗粒,当它们存在于某些化妆品和/或个人护理配方和悬浮液中时,表现出优异的除臭和吸油性能。未涂覆的硅酸钙具有较高的pH值,可能会对这些化妆品和/或个人护理组合物产生不良影响,从而使整个组合物对其预期用途无效,特别是如果硅酸钙以高负载水平的常规状态存在。或者,如果个人护理组合物中存在某些物质具有足够低的pH值,这些硅酸钙的效果也可能受到影响。因此,这种新型涂覆/处理的硅酸钙允许高负载这种有益的除臭/吸油添加剂存在于化妆品和/或个人护理配方中,而不会引起任何明显的不稳定问题或黏度修改问题,或者允许与这些低pH物质共存,而不会对硅酸钙本身的性能能力产生任何明显的降低。此外,本发明还包括这些新型涂覆硅酸钙颗粒的某些个人护理组合物。
