摘要
研究了钡钇复合氟化物体系中Eu2+的光谱性质和变化规律;讨论了影响Eu2+光谱的因素,特别是氧的存在对Eu2+激发和发射能量的影响,发现在BaYF5基质中Eu2+对Tb3+的有效能量传递。
The relation between the content of YF3 and oxygen in the host lattice and lumi-nescence change of Eu2+ in BaF2-xYF3 has been studied. The energy transfer frotn Eu2+toTb3 in Ti-doped BaYF, was observed. The emission strength of Eu2+ was found to be re-duced greatly and the decay time of the luminescence of the luminescence of Eu2+ was shortened due to the energytransfer from Eu2+ to Tb3+.
