NOVELTY - The process for metallization of a silica glass monolith, comprises irradiating the monolith by a laser beam, metallizing the monolith by immersing the monolith in an autocatalytic bath containing a first metal and an electrolytic bath containing a third metal. The monolith undergoes a doping step in which nanoparticles, ions and metals of second metal are incorporated into the monolith volume so as to create metal patterns of the first metal at surface of the monolith. The doping step is carried out by impregnating the monolith prepared by the sol-gel from a precursor.    USE - The process is useful for metallization of a silica glass monolith for making glass electrodes, electronic and/or electric glass circuits and metal patterns including decorative patterns on the surface of a glass object (all claimed), where the monolith is further useful for making energy electrodes on solar cells and in industrial applications including biology (microarrays), telecommunications, photonics (microreflectors), microfluidics, art and decoration (decoration of glasses and bottles).    ADVANTAGE - The process is capable of economically and precisely metallizing the silica glass monolith with high selectivity, good spatial control and less power thus providing easy manufacture of glass electrodes with great fineness, improved resistance, good adhesion to the surface of the monolith and good performance.    DETAILED DESCRIPTION - The process for metallization of a silica glass monolith, comprises irradiating the monolith by a laser beam, metallizing the monolith by immersing the monolith in an autocatalytic bath containing a first metal and an electrolytic bath containing a third metal. The monolith undergoes a doping step in which nanoparticles, ions and metals of second metal are incorporated into the monolith volume so as to create metal patterns of the first metal at surface of the monolith. The doping step is carried out by impregnating the monolith prepared by the sol-gel from a precursor consisting of impregnation of gold ions of the second metal at a concentration of 5x 10-5 to 10-4 M and by melting silicon dioxide powder comprising particles or metal ions of the second metal. The laser beam used for irradiation has a wavelength at an interval of (240 nm, 270 nm), and is emitted by a laser emitter of nanosecond or femtosecond type. An INDEPENDENT CLAIM is included for a silica glass monolith.
