description 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. La présente invention concerne un procédé de dépôt physique en phase vapeur à basse pression permettant le dépôt de compositions de phosphore en film mince à éléments sulfure multiples destinés à des dispositifs électroluminescents. Ce procédé comprend une source thermique, laquelle comprend un composé polysulfure qui fournit à cette source des espèces chimiques sulfure pour un dépôt de film de phosphore et/ou un recuit. Ce procédé convient particulièrement pour le dépôt de phosphore destiné à des afficheurs électroluminescents ac en couleur utilisant des couches diélectriques de film épais avec une constante diélectrique élevée.
