An encapsulated device comprising: - an organic optoelectronic component (C) having at least one so-called sensitive surface, needing to be protected from oxygen and/or water vapour; and a multilayer encapsulation structure covering at least said sensitive surface, comprising at least one layer of organic material (O) interposed between first (B1) and second (B2) barrier layers made from non-metal inorganic material impermeable to oxygen and water vapour; characterised in that said barrier layers are made from a material chosen from a stoichiometric metal oxide, stoichiometric silicon oxide and a silicon oxynitride, and produced by atomic layer deposition, and in that said multilayer encapsulation structure also comprises at least one so-called active layer (A) containing a non-stoichiometric oxide having an oxygen vacancy, also interposed between said first and second barrier layers. A method for encapsulating a component having at least one so-called sensitive surface, needing to be protected from oxygen and/or water vapour, by producing such a multilayer encapsulation structure. |
