Abstract
The luminescence of Pr3+ in gadolinium sulfate hydrate is reported for 195 nm laser excitation. The Pr3+ ion acts as a sensitizer of the hos t lattice emission. The pr(3+) --> Gd3+ energy transfer occurs in two different ways. In the octahydrate the transfer occurs from the lowest component of the 4f5d configuration of Pr3+, but in the samples with less water there is energy transfer from the S-1(0) level of Pr3+ to s everal Gd3+ levels. The Pr3+ emission in the two modifications is, of course, also strikingly different.
