dc.description.abstractFour uranyl oxide hydrate phases with heavy lanthanide ions, [Ln(UO2)2O3(OH)]·0.5H2O [Ln = Tb (1), Dy (2), Ho (3) and Yb (4)], have been synthesized under hydrothermal conditions at 240 °C and characterized. SEM-EDS revealed that these phases have very similar thin plate morphologies with a U to Ln atomic ratio of 2 : 1, which is further confirmed by TEM-EDS. Their high magnification TEM bright field images showed small crystalline domains (∼2–5 nm) with preferred crystal orientations. Both XRD and TEM SAED confirmed that they crystallize in the trigonal crystal system with the P[3 with combining macron]m1 space group. Raman characterization revealed the typical vibration modes for the uranyl units with the calculated U[double bond, length as m-dash]O bond lengths are comparable to the values reported for other UOH phases with d-transition metal ions as the interlayer species. The possible presence of a pentavalent uranyl unit has been ruled out by UV-vis-NIR spectroscopy. The thermal and optical properties have also been investigated and reported. © Royal Society of Chemistry 2025.en_AU
