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.

Synthesis Procedure

This article reports on the synthesis procedure of ZnO nanoparticles/nanofibers structure by electrospinning method using Zinc acetate and polyvinylpyrrolidone (PVP) surfactant as reagents and evaluates their luminescent properties. The microstructure of ZnO nanoparticles/nanofibers was observed by FE-SEM. The phase formation of ZnO nanoparticles/nanofibers was studied by XRD. ZnO nanoparticles/nanofibers structure shows strong luminescence centering at 660 nm, which has potential applications in solid-state lighting.
