Abstract

CaTiO

:Pr

based pearlescent pigments with fluorescent were prepared by ultrasonic-assisted dispersion technique. The samples were characterized by fluorospectro-photometer

laser particle size analyzer

X-ray diffraction

scanning electron microscopy and automatic colorimeter

respectively. The results show that the sample obtained from TiO

-mica pearlescent pigments with CaO coating ratio 5.3% and calcinating at 900 ℃ for 150 min gives a narrow particle size distribution (the average diameter is 24.34 m) with a homogeneous

dense and smooth surface. It gives white color under the solar light. The characteristic color(

) of the sample is (89.03

-1.29

1.00). The maximum emission wavelength is a red light of 613 nm under the excitation of ultraviolet at 304 nm

corresponding to the transition for

. The average fluorescent lifetime is 154.50 s.
