The structure of X-ray photoelectron spectra of light actinide compounds

“…The question of why the experimental dependence [see Fig. 42, Eqn (15)] is approximately linear was considered. The dependences of the photoionisation cross-section s(An4f 7/2 ) and s(An5f) on the number of An5f electrons n 5f (see Refs 53,81) are shown in Fig.…”

Effect of TeO2 on Near‐Infrared Emission from Bismuth Centers in Borogermanate Glasses

“…The observed peak can be decomposed into a peak centered at 573 eV and another peak at about 576 eV, correspond to the binding energy of the Te metal and TeO 2 , respectively. [27][28][29] The presence of elemental Te is further confirmed by Raman spectra. Figure 4(b) shows the Raman spectra of the glass samples GTB0, GTB0.1, and GTB3.…”

Preparation and Dielectric Characterization of Lead‐Free Niobate Glass‐Ceramic Composites Added with Lu2O3

“…As the radii of Ba 2+ , Na + , Lu 3+ , Nb 5+ are 1.34, 0.97, 0.85, 0.69 A, respectively, the medium Lu 3+ is prone to occupy both the A 2 site in T. T. B. structure where Ba 2+ locates and the A site in C. P. structure where Na + locates. 11, 12 Figures 2(a)-(d) display the scanning electron micrographs of niobate glass-ceramics added with Lu 2 O 3 from 0.5 to 3 mol%, respectively. Crystal grains with submicrometer size were uniformly distributed in the glass matrix.…”

“…13,14 The significant decline of dielectric constant when the Lu 2 O 3 addition exceeded 1 mol % was most likely due to the broad generation and wide spread of LuNbO 4 which is a typically low permittivity crystalline phase. 12 The dielectric loss tangent was effectively controlled in the range between 0.014 and 0.017. Compared with other dielectric glass-ceramics, its much lower dielectric loss is of more technical and practical significance.…”
