Abstract

We present here the syntheses and optical properties of three phosphates, namely, AM(PO4)2 (A = Pb2+, M = Ti, Ge; A = Sr2+, M = Ge). Thereinto, PbGe(PO4)2 features a strong green broad-band emission peaking at 508 nm at room temperature when excited by UV irradiation. Its luminescence properties, decay time and Commission Internationale de l'Éclairage (CIE) chromaticity index have been determined. Additionally, the photoluminescent properties of its Eu3+-doped powders have also been investigated. Finally, the calculations of energy band structure and density of states have been performed to construct an available model to explain a possible mechanism of electron transition.
