- Opis:
- A correlated set of experiments was performed with a view to study the effect of trivalent bismuth upon some properties of NaCl, KCI and RbCI crystals. For NaCI the effect of BiO$\text{}^{+}$ ions was also investigated. It was stated that: 1. The hydrolytic properties of bismuth are responsible for the formation of BiO$\text{}^{+}$ centres also in crystals doped with BP$\text{}^{3+}$ ions. 2. During all experiments performed, the dopant remains in the form of trivalent cations. 3. Optical absorption spectra of bismuth are similar to those characteristic of other heavy metal ions with the s$\text{}^{2}$ electronic configuration. 4. The charge excess of BP$\text{}^{3+}$ ions is compensated by cation vacancies whereas for BiO$\text{}^{+}$ ions the preferential bonding between Bi$\text{}^{3+}$ and O$\text{}^{2-}$ serves for the charge compensation.
