dc.description.abstractLuminescent nanomaterials have been mainly investigated in recent years because of significant differences in structure and performance from the bulk [1,2]. Most preparation methods of nanosized luminophores need high temperatures or complicated experimental procedures. Rare earth (RE) 5-Sulfoisophthalic acid complexes (RE(STMA)·4H2O) decompose to rare earth sulfates RE2O2SO4:Eu3+ in one step at low temperature, the compounds were annealed at 500, 600, 700, 800, 900 and 1000 °C [3]. This work reports a new low temperature preparation method of the Y2O2SO4:Eu3+ nanomaterials based on benzenecarboxylate method precursors. TGA analyses (Fig. 1) show on event from 35 to 175 °C corresponding to the loss of 4 water molecules and only one decomposition event, from 490 to 670 °C (loss of organic moiety). The XRD confirms the obtainment of Y2O2SO4:Eu3+ materials without the presence of other phases up to 900 °C, after this temperature Rietveld refinement show formation of Y2O3. The excitation spectra (Fig. 2) exhibit the LMCT O→Eu band centered at 275 nm and the intraconfigurational 4f transitions of Eu3+. The excitation spectra show similar features independently of the annealing temperature, with the presence of an extra low intensity broad band in the compounds annealed at 500 and 600 °C, owing to oxycarbonated. The emission spectra (Fig. 3) exhibit only the intraconfigurational 4f transitions of the Eu3+ ion, with the presence of transitions arising from the 5DJ (J: 0, 1 and 2).pt_BR
