Abstract
PURPOSE: A three-layer a.c. electroluminescent element with excellent luminescence characteristics, prepd. by use of a fluorescent membrane consisting of CaS or SrS doped with Ce or Eu.
CONSTITUTION: Y2O3, etc. is deposited on a glass substrate equipped with a transparent electrode by electron beam vacuum deposition to form an insulating membrane, on which a fluorescent membrane is formed by the vacuum deposition of a vaporizing source consisting of CaS doped with about 0.08atom% Ce. After the fluorescent membrane is annealed at about 400W1,000°C in an H2S-N2 gas mixt., Y2O3 is deposited again to form an insulating membrane, on which an electrode is formed by the vacuum deposition of Al to obtain an electroluminescent element emitting a green light. It is possible to obtain a red or blue luminescent element respectively by use of CaS:Eu or Sr:Ce as a source of the vacuum deposition.
