We have investigated at optimal temperature the X-ray detection characteristics of two TlBr crystals by the Traveling Molten Zone (TMZ) technique. The resistivities were typically 1.5 10 10 O cm at room temperature, increasing to (1.1–1.7) 10 12 O

Thallium bromide (TlBr) has attracted attention as an exceptional radiation detector material. Due to its high atomic number (81 for Tl, 35 for Br) it has excellent stopping power for hard X-ray and gamma rays and due to its high bandgap (2.7 eV) its

TlBr is relatively unique amongst semiconductors, in view of its very high density coupled with its large band-gap. Infact, its density (7.5 g cm -3 ) is comparable to bismuth germanate and thus it has excellent absorbing power for hard X-and gamma r
