Abstract

Vacuum ultraviolet (VUV) excitation and emission properties of a new Tb³⁺-activated green-emitting phosphor with huntite-type gallium borate, LnGa₃(BO₃)₄:Tb³⁺ (Ln = Y, Gd), are investigated. Overall absorption bands are in the range of 120-250 nm and can be tentatively interpreted in terms of the charge transfer transition from host to rare earth ions and the Tb³⁺ activator. Additionally, an appropriate atomic ratio of Y³⁺/Gd³⁺ in the host compound enhances both the excitation and emission efficiency under VUV excitation. Enhanced absorption efficiency for the VUV light makes these novel phosphors the prominent luminescent materials with plasma-discharge conditions, by converting the VUV radiation to the visible light.
