Synthesis and study on optical properties of CeO2-Mg(OH)(2) and inverted Mg(OH)(2)-CeO2 nanocomposites

Abstract

Well-crystalline CeO2-Mg(OH)(2) and inverted Mg(OH)(2)-CeO2 nanocomposites were successfully synthesized by a facile 'one-pot' chemical precipitation method at low temperature. The crystal structure, morphology and optical properties of the CeO2-Mg(OH)(2) and inverted Mg(OH)(2)-CeO2 nanocomposites were investigated using X-ray diffraction, TEM, FTIR, UV-vis absorption and PL spectrometer. The photoluminescence study revealed visible light emission for the nanocomposite. Interestingly, significant red shift observed for Mg(OH)(2)-CeO2 nanocomposites. The optical tuning nanocomposites can be used for the optoelectronic applications.
