- Uranium(3+) doped single crystals of RbY$\text{}_{2}$Cl$\text{}_{7}$ with a uranium concentration of 0.05% and 0.2% were grown by the Bridgman-Stockbarger method using RbU$\text{}_{2}$Cl$\text{}_{7}$ as the doping substance. Polished plates of ca. 5 mm in diameter were used for measurements of luminescence and excitation spectra. Since the U$\text{}^{3+}$ ions occupy two somewhat different site symmetries, a splitting of all observed f-f bands was observed. The analysis of the spectra enabled definitively an assignment of 22 crystal field bands for both site symmetries as well as the total crystal field splitting of the ground level, equal to 473 cm$\text{}^{-1}$ and 567 cm$\text{}^{-1}$ for the first and second site symmetry, respectively.
