The effect of supersaturation levels on the segregation coefficient of deuterium in K(H1−xDx)2PO4 crystals using Raman spectroscopy

Abstract

The deuteration level of K(H1−xDx)2PO4 (DKDP) crystals was measured by Raman spectroscopy and non-critical phase matching (NCPM) temperature experiments. Our results indicate that the PO4 vibration peak of the DKDP crystals shifted towards lower wavenumbers with increasing deuterium concentration. A different deuterium content was found between crystals grown from similarly deuterated solutions but with varying degrees of supersaturation. The NCPM temperature experiments confirm that the deuterated partition difference was about 10% when the deuteration level was moderate (30–70%) at different supersaturation levels. We found that 1% deuterium content corresponds to a 0.61 °C NCPM temperature difference.
