Abstract

Oxygen doped zinc telluride is a bright scintillator with one of the highest X-ray conversion efficiencies. These properties make it an ideal choice for wide range of X-ray imaging applications in biology and medicine. With an emission wavelength of 680 nm it is ideally suited for use with silicon imagers such as CCDs. In this paper we report a new co-evaporation process where the oxygen dopant concentration in the evaporated film is controlled by simultaneous evaporation of zinc oxide and zinc telluride charge. To date we have fabricated as large as 40 cm² area films measuring 50 μm to 500 μm in thickness. The fabrication and characterization details of these and other films are discussed in this paper.
