Abstract:
1. A glass thin film derived from a thin film of photosensitive sol-gel doped with an organometallic photosensitizer, said organometallic photosenitizer having a formula R-M-X, where X is a photolabile moiety, M is a metal, and R is a volatile organic compound, wherein said thin film of photosensitive sol-gel has a thickness in excess of one micron, is exposed to light in at least one region to unbind X constituents from M constituents of said photosensitizer within said at least one region and to bind the resulting M constituents to the sol-gel, and is heat treated to drive off the unexposed photosensitizer and unbound X constituents and to permanently bind the M constituents to a sol-gel derived glass matrix and thereby form said glass thin film, and wherein said heat treatment is carried out in a manner that does not cause lateral shrinkage or cracking of said glass thin film.
