摘要：

The absorption spectrum of Pr3+ in LaF3, LaCl 3, CaF2, Pr(Y)Cl3·6H2O, and Pr2(SO4)3·8H2O was investigated. Evidence for the 1S0 level in Pr 3+:LaF3 at 46 986 cm-1 is presented; this level was not observed directly in absorption in any of the other matrices studied. An analysis of the 13 observed levels in Pr3+:LaF3, based in part upon a re-examination of the experimentally observed crystal-field components of certain levels, gave the following electrostatic, spin-orbit, and configuration-interaction parameters: E1=4559.0, E 2=21.954, E3=467.75, ζ4f= 744.44, α= 15.294, β= -669.02, γ= 1411.8, with an rms deviation=33 cm -1.
