Improvement of Luminescent Characteristics of BaGd₄Si₃O₁₃:Tb Green VUV Phosphor by F-Incorporation

Abstract

Luminescent characteristics of BaGd₄Si₃O₁₃:Tb phosphor powder including fluorine, which is synthesized at about 1000°C, have been investigated. This phosphor shows the green emission due to Tb³⁺ under VUV excitation. By incorporation of F ion based on lowtemperature synthesis, the photoluminescence excitation band lying in the wavelength region from 130 to 170nm increases drastically in comparison to BaGd₄Si₃O₁₃:Tb phosphor synthesized at 1550°C. This phosphor is a candidate for a green PDP phosphor for both 147nm resonance line and 172nm excimer band of Xe plasma.
