Europium activated lanthanum phosphate were in situ formed within polymeric hydrogels as templates (polyacrylamide and polyacrylic acid) and the resulting sintered phosphors were obtained. Luminescence properties of cross-linked gels with LaPO4:Eu3+ were investigated by fluorescence and the results show the emission increased from 25 degrees C to 85 degrees C. Calcinated sample could exhibit distinguished D-5(0) (->) F-7(1) transition with orange-red color, which indicated Eu3+ ions occupy in the crystal lattice with inversion symmetry. More importantly, the products fabricated by hydrogel assembly show higher emission intensities compared with convention method. (C) 2012 Elsevier B.V. All rights reserved.
