Abstract

Abstract: Rare earth cyanurates were prepared by exothermic solid‐state metathesis reactions of appropriate proportions of A(OCN) (A = K, Rb, Cs) and RE Cl3 ( RE = La, Ce, Pr) at 500 °C. A DTA study of this mixture revealed the reaction to occur around 450 °C. The crystal structure of RbLa2 Cl(O3 C3 N3 )2 was refined from a powder X‐ray diffraction pattern. Homologous A RE 2 Cl(O3 C3 N3 )2 compounds with A = K, Rb, Cs and RE = La, Ce, Pr were indexed isotypically. Photoluminescence and reflection properties of doped samples and an infrared study are reported. Abstract : Rare earth metal cyanurates were prepared by solid‐state metathesis reactions and characterized as A RE 2 Cl(O3 C3 N3 )2 (A = K, Rb, Cs and RE = La, Ce, Pr). Photoluminescence properties of Eu 3+ and Tb 3+ doped Rb RE 2 Cl(O3 C3 N3 )2 samples were studied by means of luminescence and reflection spectroscopy.
