| Abstract: | Spectra properties of Ce3+ ions and Eu2+ ions in KZnF3 were studied and energy transfer from Ce3+ to Eu2+ was observed in co-doped with Ce3+ and Eu2+ systems. Quantum yields of energy transfer were calculated. The investigated mechanism of energy transfer is electric dipole-dipole interactions. We also noticed that the existence of Ce3+ is conductive to observe f-f transition emission of Eu2+ ions. |
