Abstract
Na[Ln(edta)(H2O)n] (Ln = Dy, Ho, Yb and Er, n = 1-3) complexes were synthesized using lanthanide salts and Na4(edta). The synthesized lanthanide complexes were characterized using different techniques including elemental analysis, UV-Vis, FT-IR and fluorescence spectroscopy. Their structures were also optimized using DFT method. Then, the complexes were refluxed in the presence of a mixture of Al(OH)3 and H3BO3 for 24 h. The reaction mixture was then calcined at 400°C for 5 h. The obtained powder as a new phosphorescent pigment was dispersed in water and acrylicpolyurethane resin, and new phosphorescent pigments were finally prepared by adding different percentages of lanthanide oxides to the original pigment. The prepared phosphorescent pigments were investigated using XRD, XRF, and solid state phosphorescence spectroscopy.
