| titleOfInvention | Luminescent sulfides of monovalent and trivalent cations |
| abstract | LUMINESCENT SULFIDES OF MONOVALENT AND TRIVALENT CATIONS ABSTRACT A family of luminescent materials or phosphors hav-ing a rhombohedral crystal structure and consisting essenti-ally of a mixed host sulfide of at least one monovalent host cation and at least one trivalent host cation, and containing, for each mole of phosphor, 0.0005 to 0.05 mole of at least one activating cation. The monovalent host cations may be Na, K or Rb and Cs. The trivalent host cations may be Gd, La, Lu, Sc and Y. The activating cations may be one or more of trivalent As, Bi, Ce, Dy, Er, Pr, Sb, Sm, Tb and Tm; divalent Eu, Mn, Pb, and Sn; and monovalent Ag, Cu, and Tl. The novel phosphors may be used in devices to convert elec-tron-beam, ultraviolet or x-ray energy to light in the visible spectrum. Such energy conversion can be employed for example in fluoroscopic screens, and in viewing screens of cathode-ray tubes and other electron tubes. |
