The relationship between the energy level position, energy splitting of the s1p1 configuration of selected cations and a host was studied. Results indicated that the position of the A, B, and C bands of Sn2+ and the A and B bands of In+ and Tl+ decreased linearly with an increase in the environment factor (he) of the host. A corresponding empirical formula was determined. Calculated values for the A and B bands of the free-ions In+ and Tl+ were in od agreement with experimental results. The largest error was from the B band of Tl+ and the deviation ratio was only -7.34%. Spacings for the energy levels A, B, and C become smaller because high energy level energies drop faster as he increases. By comparison, we found that the sensitivities of the A and B band energies of Sn2+, In+, and Tl+ to the host were different. The greatest change was observed for the Sn2+ ion and the In+ ion energy change was the smallest. More importantly, we found that the A, B, and C band energies splitting tendency for Sn2+, In+, and Tl+ also decreased as he increased even without splitting.
