Abstract
The chemical vapor deposition of a single phase of a double metal oxide having a stoichiometric ratio results in a fully dense film. The film is deposited by polycondensation of a partially hydrolyzed precursor reacted from water vapor mixed with a volatile, metalorganic precursor having the desired stoichiometric ratio. The film may be annealed to form a perfect crystal of stoichiometric, single phase, double metal oxide having substantially improved optical characteristics for laser light transmission and other electro-optical applications.
