Abstract

Comprehensive studies have been carried out of the interconnection of the properties of the initial powders and characteristics of optical scintillation ZnO ceramics obtained by uniaxial hot pressing. It is established how the lattice parameters, the texture, and the transparency of the ceramic samples depend on the type of powder. The x-ray luminescence intensity of the optical scintillation ZnO ceramics, with an emission wavelength peak at 517 nm, equals about 50% of that for CsI : Tl and is comparable to that of GOS : Pr, Ce ceramic, with a mean fluorescence time of 1.0–1.6 µs. The total transmittance of 1.0-mm-thick ceramic samples is about 45% at a wavelength of 517 nm.
