In this paper we present a comparative optical study of praseodymium and praseodymium/ytterbium-doped lutetium double phosphates in the wide spectral range (VUV-IR) and for various concentrations of the activators. The absorption and emission spectra of Na 3 Lu(PO 4 ) 2 :Pr 3+ and Na 3 Lu(PO 4 ) 2 :
