Comparison of emitted color by pure Gd2O3 prepared by two different methods by CIE coordinates

Monoclinic and cubic Gd2O3 phosphors were prepared by using two different methods solution combustion synthesis and solid state reaction method. The present paper deals with comparison of specific color emitted by the pure Gd2O3 phosphors prepared by combustion synthesis and solid state reaction methods. The Commission International de I'Eclairage (CIE) coordinates for combustion synthesized Gd2O3 phosphor and for the solid state synthesized Gd2O3 phosphor X = 0.207 and Y = 0.206, and X = 0.29 and Y = 0.29 respectively.
