Abstract

A simple hydrothermal method to fabricate dysprosium hydroxide nanomaterial with fully tunable morphologies without any catalysts or templates was presented. Analytical method such as XRD, FESEM, TEM, EDS were employed to characterize the morphology and microstructure of the as-synthesized products. The results reveal that the pH value changed by adjusting ammonia concentration of the solution and dysprosium hydroxide materials with the fibers-sheets-fibers morphology evolution could be obtained. The pH variation is found to play a key role in the morphology evolution. Furthermore, a possible growth mechanism of morphological evolution of the as-prepared dysprosium hydroxide was briefly discussed. Photoluminescence measurement shows that the products have two emission peaks around 490 and 575 nm, which should come from the electron transition from 4F9/2 to 6H15/2 levels and 4F9/2 to 6H13/2 levels, respectively.
