A Spectroscopic Investigation of Eu³⁺ Incorporation in LnPO₄ (Ln = Tb, Gd_1-xLu_x, X = 0.3, 0.5, 0.7, 1) Ceramics.

ABSTRACT: We have investigated the incorporation of the luminescent Eu³⁺ cation in different LnPO₄ (Ln = Tb, Gd_1-xLu _x , x = 0.3, 0.5, 0.7, 1) host phases. All samples were analyzed with powder X-ray diffraction (PXRD), Raman spectroscopy, and site-selective time-resolved laser-induced luminescence spectroscopy (TRLFS) directly after synthesis and after an aging time of one year at ambient conditions. The PXRD investigations demonstrate the formation of a TbPO₄ phase in an uncommon anhydrite-like crystal structure evoked by a pressure-induced preparation step (grinding). In the Gd_1-xLu _x PO₄ solid solution series, several different crystal structures are observed depending on th
