The CoFe2O4/TiO2 magnetic nano-photocatalysts has fairly good magnetic property. The X-ray diffraction, transmission electron microscopy and ultraviolet-visible technique were used to analyze the phase structure, size and spectrum response scope of the samples. The XRD indicated the anatase TiO2 was formed when TCF modified by plasma. The size of CoFe2O4 particles was about 20 nm. The diameter of CoFe2O4/TiO2 particles is in the range of 30~40 nm. So the shell of TiO2 enwraps closely around the core and the thickness is in the range of 10~20 nm.

运用VSM技术对样品磁性能进行研究,结果表明:等离子体修饰后的复合材料仍具有较高的饱和磁化强度,可在外加磁场作用下实现催化剂在水中的分离与回收;样品的XRD、TEM和UV-Vis分析测试结果表明:等离子体修饰后的复合材料有锐钛矿型TiO2存在;TEM谱图显示磁核CoFe2O4的平均粒径约为20 nm,TCF复合粒子的粒径约为30~40 nm,TiO2包覆层的厚度为10~20 nm。

Photoluminescence properties of ZnSe/silica gel-glasses were investigated by an advanced spectrum system. Excitated by laser of two different wavelength, the electron transition occurred in two different relaxation approaches. Interband radiation spectra and the surface defect radiation spectra of ZnSe nanoparticles were obtained. The correlation between the wavelength of eradiated light and the incident light verifies that the electronic-hole structures change with the size of the nanoparticle.

利用先进的稳态光谱测试系统研究了ZnSe/SiO〓凝胶玻璃纳米复合材料的光致发光特性,凝胶玻璃基纳米复合材料样品中观察到不同波长激发光激发样品,导致激发态电子经两种不同的弛豫途径的辐射跃迁发光,即ZnSe纳米粒子的带间发射光谱和ZnSe纳米粒子的表面缺陷态发光,辐射光的波长与入射光的波长是连续相关的,证实了凝胶玻璃中ZnSe纳米粒子存在随尺寸变化分立的能级结构。

A sample is put on the table which is processed into a inclined plane on the filmed plane, and two interfaces of a film are focalized, then the thickness is read out that is a difference between the heights of two interfaces of a film.
