ABSTRACT:
The present invention includes barrier coatings and methods for reducing or preventing chemical reaction between the discharge medium and arc tube wall material in discharge lamps. The barrier coatings comprise nitride layer exposed to the discharge medium formed from one or more of aluminum, boron, scandium, yttrium, or the lanthanides. In another aspect, the present invention includes methods of forming coatings on the inner wall of arc tubes by introducing two or more precursors into the arc tube chamber and pyrolitically reacting the precursors to form layers for the coating.
