A new method for determination of crystallinity by X-ray dffraction is proposed. The data of the intensity for amorphous phase diffraction are only used, while the ones for crystalline phase diffraction that must be used in the conventional methods are neglected. The method can be quickly and easily used for substances containing one or more than one crystalline phase. The data are treated by the least square method.The crystallinity of catalystic molecular sieve zeolite ZSM-5 and micro-crystalline glass has...

A new method for determination of crystallinity by X-ray dffraction is proposed. The data of the intensity for amorphous phase diffraction are only used, while the ones for crystalline phase diffraction that must be used in the conventional methods are neglected. The method can be quickly and easily used for substances containing one or more than one crystalline phase. The data are treated by the least square method.The crystallinity of catalystic molecular sieve zeolite ZSM-5 and micro-crystalline glass has separately determined. It is then examined that the proposed method is correct.

本文提出了一种用X射线衍射测定结晶度的新方法,仅使用无定型相的衍射强度数据,省去了常用方法所必须读取的结晶相衍射强度数据。方法合理,简便易行,既可测定含单一晶相纯物质的结晶度,也可以测定含多种晶相混合物的结晶度。数据处理采用最小二乘法。并对催化剂ZSM—5沸石分子筛和微晶玻离的结晶度分别作了测定,从而验证所提出的方法是正确的。

A pure crystalline form of CaS and its Mn2+doped phosphors were prepared for the first time by microwave radiation method(MRM). The crystal structures and the luminescent properties of CaS∶Mn2+ were determined. The influence of different Mn2+ concentration on luminescent properties of these phosphors was discussed. It indicates that MRM is a promising method for synthesis of inorganic phosphors. 

用微波辐射法合成了CaS∶Mn2+橙红色荧光化合物,用XRD测定了它们的晶体结构,系统考察了各种不同浓度下的Mn2+离子激活剂对发光性能影响.初步认为,微波辐射能使Mn2+离子在CaS基质晶格中均匀扩散,并能提高激发剂的掺入量,阻止Mn2+离子的簇集,延缓Mn2+离子对的形成.合成方法可得到晶相纯、粒度细小均匀、稳定性高、防潮性好和发光效率高的CaS∶Mn2+荧光体.

A pure SrS host and SrSCe3+,K+ phosphors with blue color were prepared by microwave radiation method (MRM) first time.The crystal structures were determined by XRD.The influence of different Ce3+ concentration on luminescent properties of these phosphors was discussed.The experimental results show that MRM compared to the traditional high temperature solid reaction exhibits interesting features,such as rapid reaction without other protective atmosphere,SrSCe3+ phosphors with high purity,smaller particles,and...

本文首次用微波辐射法(MicrowaveRadiationMethod,简称MRM)合成了纯的SrS基质和SrS∶Ce3+,K+蓝色荧光化合物,用XRD测定了它们的晶体结构,系统考察了不同浓度的Ce3+离子对发光性能的影响。实验发现,微波辐射能使Ce3+在SrS基质晶格中均匀扩散,并能提高激活剂的掺入量,阻止Ce3+离子的簇集,延缓Ce3+离子对的形成,从而能得到晶相纯、粒度均匀和发光效率高的SrS∶Ce3+,K+蓝色荧光体。
