Preparation and Characterization of Yttrium Doping Modified LaMgB5O10 Powder by Combustion Method
摘要
Abstract
Yttrium doping modified LaMgB5O10 powder was synthetised with lanthanum nitrate hydrate (La(NO3)3·nH2O), yttrium oxide (Y2O3) as oxidant and magnesium nitrate hexahydrate (Mg(NO3)2·6H2O) as reductant by combustion method.The effects of Y doping amount, calcination temperatures and time on the synthesis of Y modified LaMgB5O10 were studied.The products were analyzed by X-ray powder diffraction (XRD), scanning electron microscopy (SEM), photoluminescence spectroscopy (PL) and ultraviolet-visible diffuse reflectance spectroscopy (UV-Vis DRS).The results show that Y modified LaMgB5O10 has the best effect when the doping amount of Y is 5%, the calcination temperature is 900 ℃ and the calcination time is 5 h.Y modified LaMgB5O10 appear strong ultraviolet absorption peak at 212-317 nm and strong emission peaks at 280-355 nm and 368-435 nm.关键词
