PCT No. PCT/DE94/00382 Sec. 371 Date Sep. 25, 1995 Sec. 102(e) Date Sep. 25, 1995 PCT Filed Apr. 5, 1994 PCT Pub. No. WO94/22975 PCT Pub. Date Oct. 13, 1994A xenon excimer (Xe2) 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: (YxGdyEuz)BO3; a mixed aluminate with the general formula: (BaEuy)MgAl10O17; a mixed aluminate with the general formula: (YxGdyEuz)3Al5O12; a mixed silicate with the general formula: (YxScyTbz)2SiO5; a mixed borate with the general formula: (YxGdyTbz)BO3; and a mixed phosphate with the general formula: (LnxCeyScwTbz)PO3. 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: (YxGdyEuz)BO3; a green fluorescent material of a mixed phosphate with the general formula: (LnxCeyScwTbz)PO3 wherein Ln is either La, Y, or Gd; and a blue fluorescent material of a mixed aluminate with the general formula: (BaxEuy)MgAl10O17.
