In a phosphor thin film comprising a matrix material and a luminescence center, the matrix material has the compositional formula: M<II>vAxByOzSw wherein M<II> is Zn, Cd or Hg, A is Mg, Ca, Sr, Ba or rare earth element, B is Al, Ga or In, and atomic ratios v, x, y, z and w are 0.005 ≤ v ≤ 5, 1 ≤ x ≤ 5, 1 ≤ y ≤ 15, 0 < z < 30, and 0 < w < 30. The phosphor thin film of quality is formed at low cost by a low-temperature process, enabling manufacture of full-color EL panels. |
