Synthesis of europium-doped yttrium hydroxide and yttrium oxide nanosheets
Source abstract
Abstract
A new approach has been developed for the preparation of Y(OH)3:Eu and Y2O3:Eu nanosheets using the sol–gel method and hydrothermal reactions. XRD patterns showed that the product was purely hexagonal-phase Y(OH)3. TEM images revealed that the nanosheets are square shaped (1 × 1 μm2) with a thickness of several tens of nanometers. In addition, it was found that cubic-phase Y2O3 nanosheets can be obtained by calcination of Y(OH)3 at 900 °C for 1 h. More importantly, the thus-prepared Y(OH)3:Eu and Y2O3:Eu nanosheet phosphors were found to exhibit a relatively high photoluminescence (PL) intensity.
