Abstract:
The La 2 Ti 2 O 7 :Pr 3+ -coated fluorescent pearlescent pigment (FPP) was prepared as follows: preparation of TiO 2 -mica pearlescent pigment; subsequently coated with lanthanum hydroxide and praseodymium hydroxide; finally treated with high-temperature annealing to form La 2 Ti 2 O 7 :Pr 3+ . The obtained samples were characterized by means of scanning electron microscopy (SEM), pan-automatic chromatis-meter, laser particle size analyzer, photoluminescence excitation (PLE) and emission (PL). It is shown that the surfaces of FPP are homogeneous, dense and smooth when pH = 8.0. Moreover, the color shifts to a green-yellow hue for FPP compare with TiO 2 -mica pearlescent pigment. Besides, strong blue emission at 504 nm and red emission at 605 nm are observed on FPP.
