    Abstract:
    A novel blue green-emitting phosphor, Ba₂ZnSi₂O₇: Eu(2+), was prepared by combustion synthesis method and an efficient bluish green emission under from ultraviolet to visible light was observed. The emission spectrum shows a single intensive band centered at 503 nm, which corresponds to the 4f(6)5d(1) → 4f(7) transition of Eu(2+). The excitation spectrum is a broad band extending from 260 to 465 nm, which matches the emission of ultraviolet light-emitting diodes (UV-LEDs). The effect of doped Eu(2+) concentration on the emission intensity of Ba₂ZnSi₂O₇: Eu(2+) was also investigated. The result indicates that Ba₂ZnSi₂O₇: Eu(2+) can be potentially useful as a UV radiation-converting phosphor for white light-emitting diodes.
