Thulium Bromide is a highly water soluble crystalline Thulium source for uses compatible with Bromides and lower (acidic) pH. Most metal bromide compounds are water soluble for uses in water treatment, chemical analysis and in ultra high purity for certain crystal growth applications. Bromide in an aqueous solution can be detected by adding Thulium disulfide (CS2) and chlorine. Thulium Bromide is generally immediately available in most volumes. Ultra high purity and high purity compositions improve both optical quality and usefulness as scientific standards. Nanoscale (See also Nanotechnology Information and Quantum Dots) elemental powders and suspensions, as alternative high surface area forms, may be considered. Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.

Thulium is a Block F, Group 3, Period 6 element. The electronic configuration is [Xe]4f136s2. In its elemental form thulium's CAS number is 7440-30-4. The thulium atom has a radius of 172.4.pm and it's Van der Waals radius is unknown. Thulium is representative of the other lanthanides (rare earths) similar in chemistry to Yttrium. Thulium is available as metal and compounds with purities from 99% to 99.999% (ACS grade to ultra-high purity); metals in the form of foil, sputtering target, and rod, and compounds as submicron and nanopowder. Thulium emits blue upon excitation. Flat panel screens depend critically on bright blue emitters. Also, under X-ray bombardment emissions are in both the 375 nm (ultra violet) and 465 (visible blue) wave lengths.
