Synthesis and Luminescence of New Ce³⁺-Doped Silicates

Abstract

Rare-earth doped phosphors has been used for optical materials. The transitions within the 4fˆn configuration are amployed in luminescent device like fluorescent lamp or display. The transitions in Ce³⁺-doped materials are between 4f levels and 5d levels. Generally the emission is efficient and occurs in wide range of energy depending on the host lattice. In this study, Ce³⁺-doped silicates, Ca₂Y₂Si₂O₉, Ca₃Y₂Si₃O₁₂, Ca₃Y₂Si₆O₁₈, Ca₂Y₈Si₆O₂₆ were synthesized and their luminescence properties were measured.
