Effect of Nd3+ on the Spectroscopic Properties of Bismuth

Dec 16, 2004In this paper, the spectroscopic properties of bismuth borate glasses doped with different Nd 3+ concentrations have been investigated. The intensity parameters Ω t (t=2, 4, 6), spontaneous emission probability, fluorescence lifetime, radiative quantum efficiency, fluorescence branching ratio, and stimulated emission cross section were determined. The highest radiative quantum efficiency of

In situ bismuth

Jan 15, 2018Bismuth (Bi) electrodes have replaced the mercury electrodes for the detection of heavy metal ions owing to their wider negative potential window, well-defined stripping response, and low toxicity . At present, Bi was often loaded onto conductive materials such as Au, boron-doped diamond (BDD),, and carbon nanotubes (CNTs) . The Au electrodes have higher catalytic activity for hydrogen

Bismuth Facts for Kids

China makes the most bismuth. Peru, Mexico, and Japan also make bismuth. Bismuth can also be recycled. This is difficult in many places because bismuth is used for things like bullets, solder, and stomach medicine that get scattered all over and cannot easily be gotten again. Uses As an element. Bismuth is used in alloys with very low melting points. Some of them melt in hot water.

Bismuth

Bismuth. Bismuth is a white, crystalline, brittle metal with a pinkish tinge. Bismuth is the most diamagnetic of all metals, and the thermal conductivity is lower than any metal except mercury.It has a high electrical resistance, and has the highest Hall effect of any metal (that is, the greatest increase in electrical resistance when placed in a magnetic field).
