Abstract：Long persistent phosphoresceoce CaAl2O4:Eu2+, Nd3+ nanoparticles were synthesized through sol-gel method. The structures and properties of the samples were analyzed by DTA, TGA, XRD, TEM and spectrometer. Results indicated that the CaAl2O4 crystalline phase was formed at 800 ℃. The particles are spherical in shape and about 20-40 nm in size. The peaks of the excitation, emission and thermoluminescence spectra shift compared with the CaAl2O4:Eu2+, Nd3+ coarse crystals. The luminescence decay includes a initial rapid part and a following slow part. The decay time lasts for about 5 h.
