Purpose and area of application:

Gomel State University offers GeO₂, GeO₂-Ag, GeO₂-Ag-Ñe, GeO₂-Ag-Eu films, and also GeO₂, GeO₂-Ag, GeO₂-Ag-Re films with protective SiO₂ coating and technology of their manufacturing. The coatings can be put on a surface of glass, quartz, silicon, germanium. Implementation of particles of silver in GeO₂ film provides the new absorbing properties that influence on increase in solar elements efficiency. Additional SiO₂ coating, which put on for GeO₂-Ag-Re film is used as a protective layer, steady against mechanical influence and action of environments (water, acids, alkalis).

They can be used for manufacturing nonreflecting coatings on optical elements of devices of night vision, heat-visors, solar elements and planar wave-guides.

Technical characteristics:

Advantages:

Sol-gel-method allows to receive coatings of high optical quality and, simultaneously, to supervise received films properties more flexibly in comparison with other existing methods (vacuum deposition, colloidal methods). Moreover, sol-gel-method simplifies technological procedure of manufacture of devices.

Commercial proposals:

Production and delivery of experimental batches, transfer of technology on the basis of license contract, rendering assistance on implementation.
