Ferroelectric ultrafine particles were fabricated with LB film technique. The experimental results showed: The ferroelectric ultrafine particles were stable with a higher coverage ratio, and had a dielectric confinement effect in the LB films. The LB film showed photoluminescence at room temperature. The fluorescence spectrum consisted of wide luminescence bands. The emission spectrum had up-conversion.
