Niobium Iodide (NbI5)-Powder introduce:
Niobium pentaiodide is the inorganic compound with the formula Nb2I10. It is a yellow, moisture-sensitive, diamagnetic solid. It forms upon heating metallic niobium with iodine.
Melting point：543 °C (1,009 °F; 816 K) sublimes
It is also used as a scintillation gamma radiation detector, typically doped with europium, due to its optical clarity, relatively high density, high effective atomic number (Z=48), and high scintillation light yield. In recent years, europium-doped strontium iodide (SrI2:Eu2+) has emerged as a promising scintillation material for gamma-ray spectroscopy with extremely high light yield and proportional response, exceeding that of the widely used high performance commercial scintillator LaBr3:Ce3+.
