CeP5O14, a new ultrafast scintillator

Abstract

CeP₅O₁₄ exhibits one emission band in the wavelength range 200–750 μm under cathode ray excitation. This band peaks at 335 nm and decays initially with τ₁=12 nsec. A somewhat slower decay with τ₂=36 nsec follows. These properties make the material suitable for fast scintillator applications, especially as a beam‐indexing phosphor in color cathode ray tubes.
