The invention discloses a doped pearlescent pigment and a preparation method thereof. The pigment uses a glass flake as a substrate; the surface of the glass flake is coated with a SiO2 or SnO2 coating; the surface of the SiO2 or SnO2 coating is coated with a doped metallic oxide coating; the doped metallic oxide coating is a coating of metallic oxide doped with at least one metallic element compound, nonmetallic element compound or the combination of the two. The glass flake after SiO2 or SnO2 coating treatment is directly coated with the doped metallic oxide coating and then calcined once so as to form the doped pearlescent pigment. The invention relates to the pearlescent pigment containing the doped metallic oxide coating. By doping the metallic oxide with different metallic element compounds and/or nonmetallic compounds, the color and glossiness of the doped pigment are adjusted; therefore, both a high-glossiness colorful twinkling effect and a soft-glossiness effect can be obtained. Moreover, the pearlescent pigment has good hiding rate as well.
