Abstract: | Samples of the empirical formula Kþ 2 Ni2þ x Co2þ ð1 xÞ ðSO4Þ 2,6H2O were grown with a partial occupation of the cations Co and Ni. Mixed crystals with good optical quality were obtained by the slow evaporation growth method. In the decomposition process, these crystals suffer a mass loss of approximately 24%, equivalent to water molecules forming octahedral coordination ions of Ni and Co. The optical characteristics of the grown crystals were measured where transmittance reached more than 80% in the wavelength range of 190e390 nm. By Raman spectroscopy, the vibrational modes of SO2 4 , H2O and of the octahedral Ni(H2O)6 and Co(H2O)6 were identified. |
