Microscopic Dynamics of Confined Water in Hexagonal Phase of REPO4 (RE=Y, La)

Abstract: Confined water, a common natural phenomenon, shows very different structural, dynamical and phase behaviour vis-à-vis bulk, and it is depended on the host-water interactions. Understanding the behaviour of confined water is important for applications as well as for understanding interface chemistry. Here, our interest is in rare-earth phosphates (REPO4) which exhibit exotic properties like high chemical stability, high luminescence quantum yield, a high energy band gap, high radiation damage tolerance, etc. A recent neutron diffraction study has confirmed the existence of confined water in the channels of the hexagonal phase of YPO4:Ce-Eu and found that these water molecules remain in the lattice even up to 450 K, and give stability to the hexagonal phase. We would like to investigate the dynamical behaviour of this confined water as a function of temperature.
