Abstract

Abstract : The single phase of Eu doped YAIG [Y3−x (Al0·9 In0·1 )5 O12 : ] powder was synthesised at 1000°C by using the coprecipitation method. The influence of phase structure and Eu doping concentration on luminescence properties was investigated using TGA, XRD, SEM and XPS. The results indicate that the coprecipitation method promotes the formation of ultrafine powders and partial substitution of In 3+ for Al 3+, leading to a slight left shift of the related peak in the XRD spectra. In addition, with the ascent of Eu 3+ concentration, the emission intensity of the sample also increases significantly.
