Luminescence properties of Europium and Terbium doubly activated yttrium Niobium/ Tantalate Phosphors under X-ray excitation

Yttrium tantalate, yttrium niobium-tantalate, and yttrium niobate doubly doped by Eu3 and Tb3 were investigated using X-ray diffraction and X-ray excitation luminescence in order to study their structural and luminescent properties. By means of X-ray diffraction, the crystallographic data for YT...
