Abstract
Abstract In this work, we proposed a facile route to coat europium oxide on the walls of SBA-15. In this method, europium nitrate hexahydrate dissolved in supercritical ethane–ethanol solution was first carried into the channels of SBA-15 at 35 °C at which europium nitrate was thermally stable. Following in situ thermal decomposition of europium nitrate at 120 °C in the supercritical solution, SBA-15/Eu 2 O 3 composites were fabricated. The composites were characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy and energy dispersive analysis of X-ray (EDAX) during the transmission electron spectroscopy (TEM) observation, and N 2 sorption analysis. TEM results indicate Eu 2 O 3 was successfully coated on the walls of SBA-15. From the analyses of XRD and photoluminescence, the as-prepared composites retained the structure of SBA-15, and exhibited the optical properties originated from Eu 2 O 3 .
