摘要

PURPOSE: To produce various optical elements such as a light emitting element excellent in durability by using a glass composite material chemical cross-linked to a glass matrix with the polymer chain such as polysilane consisting of a reticular structure of metal oxide. CONSTITUTION: This glass composite material is the one chemically cross-linked to a glass matrix having a polymer chain such as the copolymer of the polysilane, polygermane and polystannane and a reticular structure of a metal atom-oxygen atom-metal atom linkage, and the volume resistivity measured by the flat-disk electrode method while setting the voltage/film thickness at 106 V/cm is controlled to =3×106 Ω.cm. The composite material is derived by the CVD process, etc., from the polymer compds. as precursors shown by formulas I and II (M is SiGeSn, and R1 and R2 are each a 1-15C alkyl, aryl and aralkyl) and formulas III and IV (M is the same as before, R11 to R15 are the same as R1 or H except R14 ). Especially, the polysilanes of formulas III and IV are cross-linked to one another through oxygen atom, and the M-O linkage is advantageous to form a structure constituting the matrix.
