Abstract The present invention relates to a luminous rare earth metal material comprising ionic dendritic polyether-linear polyacrylic acid amphilic block copolymer and rare earth metal ion in the molar ratio of 5E(-7)-5E(-4) to 2E(-5)-1.2E(-3). The luminous compound is prepared by adding at normal temperature the water solution of lanthanides metal chloride into the water solution of ionic dendritic polyether-linear polyacrylaic acid amphilic block copolymer, and remaining stationary for about 12 hr while maintaining pH at 7.5-9. It has very high luminous efficiency and may be used in light amplification, display, anti-fake, environment probe and sensor element.
