摘要
研究了KZnF3中Ce3+和Eu2+的光谱特性，在共掺Ce3+和Eu2+的体系中，观察到了Ce3+对Eu2+的能量传递过程．计算了能量传递的鼻子效率，探讨了能量传递机理．研究发现，Ce3+的存在有利于Eu2+的f-f跃迁线状发射．
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.
