ABSTRACT:
An article, having particular use as an optical memory medium, includes a thin electron trapping photoluminescent film upon a substrate. In one preferred embodiment, a selected material is prepared in bulk, then applied in a relatively thin film to a substrate, and then heated to a sufficient temperature for a sufficient period of time such that the selected material acquires electron trapping characteristics and becomes photoluminescent. Some preferred methods of depositing the material are electron-beam deposition and sputtering. Some preferred methods of heating the material include photo crystallization and laser crystallization.
