This work presents the structural, morphological, and luminescent characterization of pure SrTiO3and SrTiO3:Eu3+powders doped with different europium atomic concentrations from 3.0 to 7.0 a.t.%. Those phosphors were prepared by pressure-assisted combustion synthesis using titanium oxide as precursor and were subjected to postannealing at 1200°C. XRD measurements indicated that undoped and Eu3+doped samples presented a single cubic crystalline phase and SEM images demonstrated that we have particles with sizes in the range of 0.2 µm–1.0 µm. Moreover, the size of the grains increases as the content of Eu3+dopant increases. A strong red emission from Eu3+ions was obtained by photoluminescence under excitation at 396 nm and confirmed by cathodoluminescence. All those results indicate that our red phosphors could be useful for potential applications in solid state lighting and field emission displays.

Zirconia Nanoparticles

This paper reports a tunable luminescence of europium (Eu 3+) doped zirconia (ZrO2) nanoparticles as a function of hydrothermal temperature, europium concentrations, time and pH value. The nano-sized Eu doped ZrO2 (Eu:ZrO2) particle was synthesized by hydrothermal method at the temperature of 200 °C and time up to 48 h. The nano-sized Eu:ZrO2 particles have a diameter of about 10 nm. The luminescent properties of nano-sized Eu:ZrO2 particle was enhanced in the sample when high temperature, high Eu 3+ concentration and prolonging hydrothermal time were used at pH 7. These results suggest the use of Eu:ZrO2 nanoparticles followed by thermal annealing in tuning the luminescence of Eu:ZrO2 nanoparticles which have potential applications as phosphors in solid state lighting.

Effective Energy Transfer

Na2BaMgP2O8phosphors were synthesized by a standard solid state reaction and their luminescent properties were investigated. The phase structure was analyzed by X-ray powder diffraction measurement. Under the excitation of 365nm, Na2BaMgP2O8:Tb3+, Eu3+phosphors show two color bands of green and red color due to5D4−7F5transition of Tb3+ions and5D0−7F2transition of Eu3+ions, respectively. The emission intensity of Tb3+deceased with the increasing concentration of Eu3+, which verified that an effective energy transfer occurred from Tb3+to Eu3+in Na2BaMgP2O8host. The present study indicated that the phosphors have a high potential application in solid state lighting.
