Growth and vibrational spectroscopic studies of pure and yttrium doped single crystals of trisodium barium pentachloride dihydrate

Single crystals of pure and rare earth doped trisodium barium pentachloride dihydrate have been grown by slow evaporation solution growth. The solubility of both pure and doped forms of Na3BaCl5·2H2O has been estimated. Vibrational spectra were recorded to determine the symmetries of molecular vibrations. The observed Raman and infrared bands were assigned and discussed in detail. The optical transparencies of the grown crystals were tested by UV–vis spectrophotometer.
