摘要：

The K3Lu1-xYbx(PO4)(2), Rb3Dy(PO4)(2) et K2RbHo-(PO4)(2) compounds exhibit a phase transition (rhombohedral --> monoclinic) produced by a pressure effect. For these compounds, we have determined the pressure value inducing this transition by the et amination of the evolution of infrared spectra recorded using KBr pellets obtained at different pressure. The region of the coexistence of both rhombohedral and monoclinic phases has also been determined.
