Using a rapid transport method (RTM), homogeneous crystals of intermediate compositions of the DKDP solid solution (K(H(1-x)Dx)2PO4) have been rapidly grown at constant temperatures and supersaturations. X-ray diffraction topography asserted their high crystal quality, without disorientation between growth sectors, striation, or growth bands. Micro-Raman spectroscopy showed homogeneous isotopic compositions without any drift, fluctuations, or sector segregations. These results confirm that RTM is perfectly adapted to the rapid growth of intermediate compositions of solid solutions or doped crystals.
