Films based on zinc oxyfluorides, which are transparent, electrically conductive and reflectors of infrared, are produced by gas deposition by chemical process of gas phase mixtures of compounds containing zinc, oxygen and fluorine. . The substitution of part of the oxygen by fluorine in the zinc oxide results in a very strong increase in the electrical conductivity. Vapors of diethyl zinc, ethyl alcohol and hexafluoropropene are thus reacted over a glass surface at a temperature of 400 ° C. to form a film of zinc oxyfluoride, which is transparent to vision, electrically conductive, infrared reflector and ultraviolet absorbing. Such films are useful in liquid crystal display devices, solar cells, electrochromic absorbers and reflectors, energy conservation thermal mirrors, and antistatic coatings. |
