Zusammenfassung:The subject matter of the invention is a method of obtaining a material comprising a substrate coated on at least one part of at least one of its faces with a stack of thin layers comprising at least one layer of silver, said method comprising a step of depositing said stack followed by a step of heat treatment, said heat treatment being implemented by irradiating at least one part of the surface of said stack using at least one incoherent light source for an irradiation period of between 0.1 milliseconds and 00 seconds, such that the square resistance and/or the emissivity of said stack is reduced by at least 5%, relatively, the or each silver layer remaining continuous at the end of the treatment. La presente invención se relaciona con un método para obtener un material que comprende un sustrato recubierto sobre al menos una parte de al menos una de sus superficies con un apilamiento de capas delgadas que comprende al menos una capa de plata, el método comprende una etapa de depósito del apilamiento seguida por una etapa de tratamiento térmico, el tratamiento térmico se implementa irradiando al menos una parte de la superficie del apilamiento con la ayuda de al menos una fuente de luz incoherente por un periodo de irradiación de entre 0.1 milisegundos y 00 segundos, de suerte que la resistencia cuadrada y/o la emisividad del apilamiento se reduce en al menos 5% relativamente, la o cada capa de plata permanece continua al final del tratamiento.
