Abstract

Le film mince de type naxvopo4,nh2o est électrodéposé à partir d'une solution aqueuse contenant 0,1m de sulfate de vanadyle, 1m d'acide phosphorique ajusté au ph (1,9;2;2,1). L'élaboration du film mince est réalisée par oxydation galvanostaique ou par cyclage voltampérométique. La réaction d'électrodéposition se déroule en deux étapes : l'oxydation en espèces solubles suivie d'une précipation. L'influence des paramètres de synthèse sur la prparation du film mince de naxvopo4, nh2o est étudiée. La structure cristalline des dépôts étudiée par diffraction des rayons x a été correctement indexée à la structure orthorhombique de type na0,45 vopo4 1,58h2o. L'étude morphologique est réalisée par microscopie électronique à balayage et révèle une surface homogène. La taille des cristallites calculée à partir des raies (002) (023) et (131) par l'équation de scherrer est de l'ordre de 30 nm.
