ABSTRACT:
A faceplate of a cathode ray tube is shown wherein a cathodoluminescent phosphor material 1 is deposited on glass faceplate 2. A metal nitride metal absorbing inhomogeneous film 3, where the metal is aluminum or silicon, is deposited on the back side of the phosphor material 1. To avoid unwanted reflections at the interface between the glass 2 and the phosphor 1, a homogeneous film 4 is optionally deposited on glass plate 2 prior to deposition of the phosphor film 1. Additionally, an anti-reflection coating 5 may also be optionally applied to the exterior of the glass plate 2 to eliminate reflection that would otherwise occur at the air-glass interface.
