Abstract
Figure 25 shows the single-configurational-coordinate (SCC) energy level diagram appropriate for Eu3+ in La2O2S, Y2O2S, and LaOCl. The 7F 4f6 states are not shown. They are split into seven J states spanning about 6 000 cm−1 with J between 0 and 6. They would be placed with the zero of energy at the minimum of the 7F0 parabola and with only minor offsets, with Sħω < 100 cm−1. The first set of excited 4f6 states are the 5D states, split into five J states between 0 and 4. These also have only minor offsets. The first four of these states have been identified; the J = 4 state and the other 4f6 states will be referenced only by their absorption energies in nanometers.
