Abstract

The optical properties of Nd³⁺:LaF₃ and Nd³⁺:(La_1-x,Ba_x)F_3-x (x=0.1) crystals, which were efficiently grown by the micro-pulling down method, were investigated using a vacuum ultraviolet spectrum-resolved streak camera system. The fluorescence of the Nd³⁺:LaF₃ crystal is centered at 174 nm with a full width at half maximum of 8 nm and a lifetime of 8.9 ns. On the other hand, the fluorescence of the Nd³⁺:(La_1-x,Ba_x)F_3-x (x=0.1) crystal is centered at 180 nm with a full width at half maximum of 12 nm and a lifetime of 6.1 ns. Since the (La_1-x,Ba_x)F_3-x (x=0.1) host is transparent in the vacuum ultraviolet region having a transmission edge at 160 nm, it is proposed that Nd³⁺:(La_1-x,Ba_x)F_3-x (x=0.1) is suitable as a vacuum ultraviolet scintillator and as a potential laser material.
