In general, rare earth elements exist as oxides. The luminescence mechanism of rare earth elements is determined by their own energy levels and crystal sites. When the rare earth element is in the free state, the transition of each energy level in the configuration is called parity forbidden… Read More »Luminescence of rare earth ions

Phosphorescence, another important type of excited state radiation transition, is the radiation emitted when excited molecules are deactivated to low energy states with different multiplicities. Phosphorescence is usually observed from the first excitation triplet (T;). The radiation emitted during the transition to the ground state (S,) (Kasha rule).T1→So… Read More »Generation and rate constant of phosphorescence
