Abstract

Neodymium-doped lanthanum fluoride (Nd ³⁺:LaF ₃) thin films were successfully grown on MgF ₂(001) substrates by pulsed laser deposition. Photoluminescence spectra revealed a dominant peak at 173nm with a decay time of 7.8 ns, which is similar to the results obtained from a bulk Nd ³⁺:LaF ₃ crystal. Improvements in crystalline quality and vacuum ultraviolet (VUV) luminescence quantum efficiency were achieved by substrate heating, with optimum results being obtained at 400 °C. These results would open up possibilities in the development of a light-emitting device operating in the VUV region.
