structure effect on luminescent properties

x ] powder was synthesised at 1000uC 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 3z for Al 3z , leading to a slight left shift of the related peak in the XRD spectra. In addition, with the ascent of Eu 3z concentration, the emission intensity of the sample
