Abstract: Spectra properties of Ce3+ions and Eu2+ions in KZnF3were 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.
