Abstract

Das neuartige Verfahren umfasst den Schritt der Separation von Seltenen Erden, wobei die Separation mittels zumindest einem der folgenden Verfahren durchgeführt wird, wobei mindestens ein Trennschritt durchgeführt wird: Anwendung von Kolonnen; Anwendung von Mixer-Settler; Anwendung von Ionenchromatographie. Mit diesem Verfahren lassen sich insbesondere stabilisierte Leuchtstoffe produzieren und Lichtquellen kostengünstig herstellen.
