  • Polysulfide thermal vapour source for thin sulfide film deposition
    Publication number: 20050142289
    Abstract: The present invention is a low pressure physical vapour 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 colour ac electroluminescent displays employing thick film dielectric layers with a high dielectric constant.
