Xenon excimer radiation source with fluorescent materials

摘要

A xenon excimer (Xe.sub.2) radiation source for producing vacuum ultraviolet (VUV), broad-band, molecular radiation of wavelengths shorter than 200 nm includes fluorescent materials for excitation by the VUV radiation and illumination purposes. The fluorescent materials include a mixed borate with the general formula: (Y.sub.x Gd.sub.y Eu.sub. z)BO.sub. 3 ; a mixed aluminate with the general formula: (B.sub.a Eu.sub. y)MgAl. sub.10 O.sub.17 ; a mixed aluminate with the general formula: (Y. sub.x Gd. sub.y Eu.sub.z).sub.3 Al.sub.5 O.sub.12 ; a mixed silicate with the general formula: (Y.sub.x Sc.sub.y Tb.sub.z).sub.2 SiO.sub.5 ; a mixed borate with the general formula: (Y.sub.x Gd.sub.y Tb.sub.z)BO.sub. 3 ; and a mixed phosphate with the general formula: (Ln.sub.x Ce.sub.y Sc. sub. w Tb.sub.z)PO.sub.3. In an alternate embodiment, a fluorescent lamp includes a xenon excimer radiation source for producing vacuum ultraviolet (VUV) radiation, and fluorescent materials for excitation by the VUV radiation and illumination purposes, wherein the fluorescent materials includes a red fluorescent material of a mixed borate with the general formula: (Y.sub.x Gd.sub.y Eu.sub.z)BO.sub.3 ; a green fluorescent material of a mixed phosphate with the general formula: (Ln. sub.x Ce.sub.y Sc.sub.w Tb.sub.z)PO.sub.3 wherein Ln is either La, Y, or Gd; and a blue fluorescent material of a mixed aluminate with the general formula: (Ba.sub.x Eu.sub.y)MgAl.sub.10 O.sub.17.
