Abstract

Yttrium silicate nanoparticles were synthesized by the reverse micelle method, and their optical properties were investigated. Span 80 was used as a surfactant for the reverse micelle method. The matrix of the particles was Y₂Si₂O₇. The particle size measured by scanning electron microscope was 10–20 nm. Photoluminescence of Y₂Si₂O₇:Tb,Ce nanoparticles showed typical green emission from the Tb³⁺ ion based on transition from ⁵D₄ to ⁷F_J (J = 6, 5, 4, and 3). An increase in Ce concentration increased the green emission by ultraviolet excitation because energy was transferred from the Ce³⁺ ion to the Tb³⁺ ion. The nanoparticles would be useful for various applications.
