Abstract:A series of BaLaAl3O7:xEu3+ nanophosphors have been prepared by the high‐temperature solid state reaction method. The XRD and SEM characterization results present that there exists a slight influence on the crystal structure and the average particle size of the nanophosphors while the Eu3+ ions are doped into the matrix. The intense and narrow red photoluminescence spectra have been measured under the ultraviolet excitation and there are two optimal Eu3+ concentrations of 0.8 and 12 mol%, respectively, and the… Show more
