Abstract	The room temperature IRand Daman spectra of the different M3RE(PO4)2 (M = K, Rb; RE = La, Eu, Gd) double phosphates were analysed and used to interpret the vibronic side band structure in the photoluminescence spectra. The intraconfigurational 4f-4f electronic transitions in the photoluminescence spectra of the Eu3+ doped M3 RE(PO4)2 were analysed in detail. The crystal field fine structure of the 5D0 -> 71',1 (J = 0-4) transitions was analysed accounting for the information on the crystal structure. The effect of the temperature as well as the alkali host cation was evaluated. Finally, a preliminary crystal field energy level scheme for the 7Fj (J = 0-4) ground term was deduced from the analysis of the photoluminescence as well as IRand Raman spectra.
