Abstract

The technique of standard addition in combination with powder X-ray diffraction was used to identify and quantify the amount of Ln3+ segregating into secondary phases from Ln3+ doped alkaline earth aluminates. Results indicate that Ln3+ ions are more soluble in Ca Al2 O4 than Sr Al2 O4 and Ba Al2 O4, with this being rationalized by the structural details of the A sites. These results indicate that the enhancement of the luminescence afterglow obtained by doping A Al2 O4: Eu2+ samples with Ln3+ ions is a result of much lower doping levels than previously thought. © International Centre for Diffraction Data.
