Paper Abstract

The paper presents some aspects referring to the synthesis of niobium activated yttrium orthotantalate phosphor (YTaO4:Nb), utilizable in the manufacture of X-ray intensifying screens for medical diagnosis. The influence of some preparative conditions such as activator concentration and firing regime on the crystalline structure and luminescent characteristics are investigated. Photoluminescence spectroscopy, X-ray diffraction and FT-IR spectroscopy are used to evaluate the material quality.
