Abstract :

The research and development of new VUV scintillators includes also LuLiF₄ single crystals doped by Nd³⁺. Due to their lower light yield, the Gd³⁺ codoping is studied as a tool to improve an energy transfer from the host to Nd³⁺ emission centers and increase the light yield consequently. Emission spectra and decays with respect to the different concentration of Gd and Nd ions are studied and discussed as well.
