Thallium(I) bromide (TlBr), a chemical compound, available in an ultra-pure state is a compound semiconductor; used in room temperature X- and gamma-ray detectors and blue sensitive photodetectors; used as a real-time x-ray image sensor; also used as a standard for elemental thallium.

The crystalline structure is of cubic CsCl type at room temperature, but it lowers to the orthorombic thallium iodide type upon cooling, the transition temperature being likely affected by the impurities .

A Material safety data sheet (MSDS) is available at http://www.espimetals.com/msds's/thalliumbromide.pdf. Thallium is extremely toxic and a cumulative poison which can be absorbed through the skin. Acute and chronic effects include fatigue, limb pain, peripheral neuritis, joint pain, loss of hair, Central nervous System effects, diarrhea, vomiting, liver and kidney damage.
