Abstract

The effect of NH₃ on the morphology evolution of single crystalline hexagonal-prism like Y₄O(OH)₉NO₃ and Y₂O₃ has been systematically investigated, as a function of reaction time, by using a combination of powder X-ray diffraction (XRD) and scanning electron microscopy (SEM). Rational control over the morphology has been achieved by the choice of suitable electrolytes like NaNO₃, KNO₃, NH₄NO₃, KCl and NH₄Cl in the presence of NH₄OH. We report that the cross-sectional geometry of hydrothermally grown one-dimensional Y₄O(OH)₉NO₃ crystals can be tuned from spherical to hexagonal-prism like shape by introducing a particular reagent like NH₄NO₃ in the presence of NH₄OH. An ‘oriented attachment’ mediated growth process takes place along with the ‘dissolution-recrystallization’ route which eventually resulted in the generation of the single crystals with hexagonal-prism like morphology.
