摘要

Applying inorganic ceramic layers to a substrate comprises depositing ceramic particles or molecules with a phosphor composition from a flame (2) to form a ceramic-like layer (8) on a glass substrate (7). The synthesis of the phosphor particles is carried out in-situ in the flame whilst liquid solutions of the starting materials are injected as mist (4) or corresponding gaseous components (5, 6) into the flame. Preferred Features: The flame is injected with a fuel gas based on hydrocarbons and oxygen and/or air, and a mist of one solution of the starting materials is sprayed from one or more nozzles (3) into the mixing zone of the gases.
