The phenomenon of energy transfer plays an important role in the development of luminescent materials, especially materials used for manufacturing white process of luminescence at wavelength 542nm from Tb3+ doped in silica or LaF3 can be stimulated by ultraviolet light near 227 nm. However, the excitation wavelength can be shifted to a more accessible value of 325 nm by co- doping Tb3+ with Ce3+ ions. At this wavelength Ce3+ ions absorb and then transfer the energy to the Tb3+ ions. | Interaction mechanism of energy transfer from Ce to Tb ions in silica and LaF3
