Abstract

The development and characterization of the optical properties of a neodymium(III)-doped 42.75AlF₃–33.25CaF₂–19BaF₂–5YF₃ (Nd³⁺-doped BCA-5Y) glass in the vacuum ultraviolet (VUV) region are reported. Photoluminescence peaks at 180 and 227 nm are observed upon excitation with the 157 nm emission of a F₂ laser. The dominant 180 nm emission peak is assigned to the 4f²5d–4f³ (⁴I_9/2 level) transition in Nd³⁺. This emission peak exhibits a fast, single exponential luminescence with a 16 ns decay time. The strong luminescence intensity and the fast decay time allude to its prospects for scintillator applications.
