We successfully grew langbeinite-type structures containing Ti⁴⁺ and Ln³⁺ ions asM₂Ti_2-xLn_x(PO₄)₃ crystals (M = K⁺ or Rb⁺ and Ln = Er³⁺ or Yb³⁺) by high-temperature-solution methods. We took accurate composition measurements of these crystals, payingspecial attention to the lanthanide contents. We resolved the structure of the Rb₂Ti_1.01Er_0.99(PO₄)₃ crystal and studied the evolution of this structure with the temperature. We foundthat this compound decomposed at 1323 K. We made a preliminary study to check thenonlinear optical properties of these materials, showing that the second-harmonic generationefficiency of the Rb₂Ti_1.01Er_0.99(PO₄)₃ was at least similar to that of potassium dihydrogenphosphate.
