Abstract

The luminescence properties of Eu²⁺-doped barium calcium silicon oxynitrides (general formula: Ba_4-xCa_xSi ₆ON₁₀: Eu²⁺ (x = 1.8 ∼ 2.2)) were examined, together with the preparation conditions for the solid state reaction. Firstly, the stoichiometric amounts of Ba, Ca₃N₂, SiO₂ and Si3N4 were mixed with Eu₂O₃ (activator; the molar ratios of Eu to (Ca + Ba + Eu) (= m; 0.05 to 1.0)) for the preparation of Ba_1.8Ca₂₂Si₆ON₁₀: Eu²⁺, Ba_2.0Ca_2.0Si₆ON₁₀: Eu²⁺ and Ba2.2Ca1.8Si6ON10: Eu²⁺, and then the mixtures were heated at a temperature between 1300 and 1550°C for 10 h in N₂ atmosphere. The single phase compounds, which were prepared by the heating at and above 1350°C, emitted the red color light whose wavelength could be changed from 638 to 653 nm with increasing m value from 0.05 to 1.00, due to the excitation at the wavelength of 528 nm.
