Keywords scintillators, scintillation mechanism, luminescence, energy transfer

Rb₃Lu(PO₄)₂:Ce and Cs₃Lu(PO₄)₂:Ce single crystals have been studied under γ-, x-ray and UV excitation. For all types of excitation the luminescence of these materials is dominated by a broad Ce-emission band positioned at the UV/visible light boundary. Highly efficient and relatively fast scintillation of both materials identify them as promising scintillators.
