Rapid Single Step Development of Functional oxide Coatings by a Novel Precursor Plasma Spraying Technique

P. Sujatha Devi, J. Margolis, J. B. Parise, S. Sampath and H. Herman

A novel and fast method is developed to make functional oxide ceramic coating including phosphor films by a precursor plasma spraying technique starting from a solution precursor. This process marks the first single method to develop the high temperature functional ceramic oxide like yttrium aluminum garnet (YAG) and also Europium doped Yttria (Y2O3) and YAG for display applications.
