Summary:Novel one-dimensional nanostructures of yttrium aluminum garnet were synthesized under supercritical hydrothermal conditions in the presence of organic amine molecules. In addition, the effect of different reaction parameters such as the presence of organic amine molecules, pH of the precursor solution, and the state of water (sub- or supercritical conditions) on the morphology of the final product was investigated. In this paper, considering the simultaneous effects of these different parameters, a new electrostatic model is proposed to explain the formation mechanism of the obtained nanostructures. Single crystalline one dimensional yttrium aluminum garnet (YAG) nanostructures were synthesized under supercritical hydrothermal conditions in the presence of alkylamines.
