Abstract: IR luminescence and absorption in bismuth-doped silica glass-core fibers observed recently (see [arXiv:1106.2969v1 [physics.optics]) are argued to be caused by transitions in interstitial Bi...
Впервые получены 3-мерные спектры люминесценции (интенсивность люминесценции в зависимости от длин волн возбуждения и эмиссии) легированных висмутом волоконных световодов различного состава в широком ...
We did radiotracer experiments using207 Bi to quantify the bioavailability, accumulation, and retention of bismuth in marine plankton and biogenic detritus. The accumulation of207Bi by two species of ...
Ternary system of lead-bismuth-borate glasses has been fabricated in three different compositions (PbO)x%– (Bi2O3)(50-x)% – (B2O3)50% with x = 5, 15 and 25 using the melt quench technique. The D.C. el...
Arsenic(III) tripyrazolinates and bismuth(III) tripyrazolinates of the type M(C15H12N2OX)3 [where C15H12N2OX = 3(2'-hydroxyphenyl)-5-(4-substituted phenyl)pyrazoline] have been synthesized by the reac...

期刊信息 篇名 Edge enhancement by use of moving gratings in bismuth silicon oxide crystal and its application to optical correation 语种 英文 撰写或编译 作者 Zhaoqi Wang,Hui Zhang 第一作者单位 刊物名称 Applied optics 页面 1998,Vo...
Strontium Bismuth Tantalate (SBT) ferroelectric thin films have attracted considerable attention for the development of non-volatile ferroelectric random access memories (NV-FRAMs). These films, howev...
Thin films of Bismuth oxyiodide (BiOI) were deposited, using chemical bath deposition techniques. The films were characterized using energy dispersive x-ray fluorescence (EDXRF) and Fourier transform ...
Bismuth(III) (0-25 m g/ml) is determined spectrophotometricaly at 513 nm after extraction into dichloromethane of the ion associate di-(hydrogenatedtallowalkyl)dimethylammonium tetraiodobismuthate. Th...
An electrolytic Copper Solution (ECS) was electrolyzed using platinum electrodes. Copper was obtained in solid form. In order to precipitate Cd(II), Bi(III), As(III), Sb(III) and the rest of the Cu(II...
Junctions were fabricated in vacuum of about 10-5 Torr by thermal evaporation of Sb or Bi onto chemically etched p-type silicon (100) substrates. The electrical properties were studied by current volt...
Bismuth oxide thin films have been prepared on amorphous glass substrates from non-aqueous medium using spray pyrolysis method. Characterization of the films was carried out with XRD, optical absorpti...
Interlayer sodium ions of montmorillonite were exchanged with hydroxy-bismuth polycations which were prepared from bismuth perchlorate solutions by the addition of NaOH. Assuming the charge density of...
