Effect of Phosphorus-Containing Dispersant on the Microstructure and Optical Properties of Scintillation Ceramic (Gd,Y)3(Al,Ga)5O12:Ce with Garnet Structure
Phosphoric acid ester, a typical component of commercial dispersants, affects the functional properties of Gd1.494Y1.494Ce0.012Al2Ga3O12 ceramics. In sintered ceramics, the residual phosphorus can reach up to 40–70% of the introduced amount. The admixture of phosphorus located on the surfaces of the particles activates the grain growth during sintering and leads to the formation of secondary phases of rare-earth phosphates. With increasing phosphorus concentration, the density and optical transmittance of ceramics decrease. A relatively small amount of phosphorus can improve the luminescence properties of ceramics but large amounts can increase phosphorescence and reduce the scintillation light yield.
期刊介绍：
Journal of Surface Investigation: X-ray, Synchrotron and Neutron Techniques publishes original articles on the topical problems of solid-state physics, materials science, experimental techniques, condensed media, nanostructures, surfaces of thin films, and phase boundaries: geometric and energetical structures of surfaces, the methods of computer simulations; physical and chemical properties and their changes upon radiation and other treatments; the methods of studies of films and surface layers of crystals (XRD, XPS, synchrotron radiation, neutron and electron diffraction, electron microscopic, scanning tunneling microscopic, atomic force microscopic studies, and other methods that provide data on the surfaces and thin films). Articles related to the methods and technics of structure studies are the focus of the journal. The journal accepts manuscripts of regular articles and reviews in English or Russian language from authors of all countries. All manuscripts are peer-reviewed.
