The present invention is a method for gettering undesirable atomic species from a vaporizing atmosphere during deposition of multi-element thin film phosphor compositions. The method comprises vaporizing one or more getter species immediately prior and/or simultaneously during the deposition of a phosphor film composition within a deposition chamber. The method improves the luminance and emission spectrum of phosphor materials used for full colour ac electroluminescent displays employing thick film dielectric layers with a high dielectric constant.

Method for gettering oxygen and water during vacuum deposition of sulfide films

The present invention is a low pressure physical vapor deposition method for the deposition of multi element sulfide thin film phosphor compositions for electroluminescent devices where a thermal source comprising a polysulfide compound provides the source of sulfur species for phosphor film deposition and/or annealing. The method is particularly useful for the deposition of phosphors for full color ac electroluminescent displays employing thick film dielectric layers with a high dielectric constant.
