Complex investigations of the elemental composition and optical characteristics of glass-metal nanocomposites modified by
thermo-electric-field processing are carried out. The form of the silver distribution in the glass-metal nanocomposite obtained
on the basis of soda-lime silicate glass using silver-sodium ion exchange followed by the reduction of silver during thermal
treatment in hydrogen atmosphere is determined. Main transport processes occurring in the nanocomposite under thermo-electric-field
treatment are identified. 相似文献

In this article we compare the classical monopole mass filter of von Zahn and the monopole mass filter with a hyperbolic V-shaped electrode. The experimental results and those of computer simulation for both mass spectrometers are presented. We show that the replacement of a conventional 90 degrees V-shaped electrode by an electrode with a hyperbolic profile substantially improves the peak shape of any given mass, and increases the mass resolution by a factor of 3-4 and the abundance sensitivity by a factor of 100. The potential of high analytical performance combined with electroforming techniques for electrode manufacture indicate future practical uses of such instruments.

Spectra of Eu3+ in various dielectric matrices (Gd2O3:Eu3+, Y2O3:Eu3+, Eu2O3, and mSiO2/Gd2O3:Eu3+ mesoporous particles) are studied by local cathodoluminescence. The results allowed identification of the local environment of Er3+ ions in amorphous samples and detection of the monoclinic Eu2O3 phase impurity in samples with yttrium oxide. The cathodoluminescence spectra of chemically pure Y2O3, Eu2O3, and Gd2O3 are recorded. Conclusions about the structural features of the materials are made and confirmed by other methods (XRD and EPMA). 相似文献

The rate of formation of a hydrocarbon film on the surface of a sample subjected to the action of an electron beam is studied at room temperature and in cooling a sample to the liquid nitrogen temperature. The thickness and the optical radiation transmission of such films are measured as functions of the electron beam radiation time, the sample temperature, and the level of vacuum. The film thickness is measured with atomic force microscopy. The absorption of the films is determined by comparing the cathodoluminescence intensities from a pure sample surface and from the surface covered with a film. The experimental results can be used to estimate the film formation rate as a function of the sample temperature and the vacuum and to determine the optical radiation absorption at a wavelength of 300, 360, 550, and 665 nm. 相似文献

Double incorporation of Eu3+ and Tb3+ ions into a CaWO4 crystalline lattice modifies the luminescence spectrum due to the formation of new emission centers. Depending on the activators concentration and nature, as well as on the interaction between the activators themselves, the luminescence color can be varied within the entire range of the visible spectrum. Variable luminescence was obtained when CaWO4:Eu,Tb phosphors with 0-5 mol% activator ions were exposed to relatively low excitation energies as UV (365 and 254 nm). Under high energy excitation such as VUV (147 nm) radiation or electron beam, white light has been observed.This material with controlled properties seems to be promising for the applications in fluorescent lamps, colored lightning for advertisement industries, and other optoelectronic devices. 相似文献
