Abstract
Silica-based particles coated with antimony oxide with a low refractive index and having conductivity are provided. The silica-based particles coated with antimony oxide comprise porous or hollow silica-based particles with antimony oxide coated thereon. A refractive index of the silica-based particles coated with antimony oxide is in the range from 1.35 to 1.60 with the volume resistivity value in the range from 10 to 5000 Ω/cm and the average particle diameter in the range from 5 to 300 nm, and the thickness of the antimony oxide coating layer is in the range from 0.5 to 30 nm.
