摘要：

Nanoparticles with the nominal composition Ca(0.8)Ba(0.2)Ti0(3):Pr3+ were prepared using the sol-gel process. Barium nitrate, 4-hydrated calcium nitrate and praseodymium oxide were used as raw materials. The structural evolution and decomposition processes of the precursors were investigated by powder X-ray diffraction, differential thermal analysis and thermogravimetric analysis. Crystalline Ca(0.8)Ba(0.2)Ti0(3):Pr3+ could be obtained at 700 degrees C. The photoluminescence properties of the samples were investigated using excitation and emission spectra. Ca(0.8)Ba(0.2)Ti0(3):Pr3+ nanoparticles showed strong red emission, which could be assigned to the typical (D2H4)-D-1-H-3 transition of Pr3+. Furthermore, the study found that sintering temperature and the introduction of Ba2+ influence the decay time of persistent luminescence. Copyright (c) 2014 John Wiley & Sons, Ltd.
