Mercury(I) bromide or mercurous bromide is the chemical compound composed of mercury and bromine with the formula Hg2Br2. It changes color from white to yellow when heated[1] and fluoresces a salmon color when exposed to ultraviolet light. It has applications in acousto-optical devices.[4]
A very rare mineral form is called kuzminite and has the chemical formula Hg2(Br,Cl)2.
