摘要：
The development and characterization of the optical properties of a neodymium(III)-doped 42.75AlF(3)-33.25CaF(2)-19BaF(2)-5YF(3)(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 F(2)laser. The dominant 180 nm emission peak is assigned to the 4f(2)5d-4f(3)((4)I(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.
