【摘要】 用热聚合法制备了掺Eu(DBM)3Phen螯合物的聚合物光纤,建立了团簇化铕离子相互作用模型,以此为基础研究该掺杂聚合物光纤的团簇现象。利用速率方程理论,结合光纤的抽运光透射率实验,得到所研究光纤中团簇化铕离子浓度。掺铕质量分数为0.1%,0.2%,0.3%,0.4%,0.5%,1%的聚合物光纤中团簇化铕离子的浓度分别为0.045,0.07,0.07,0.07,0.07,0.08。因此,该掺杂聚合物光纤的团簇化铕离子浓度较低且基本不随掺杂浓度的增加而增加,铕离子之间的团簇化现象不明显。更多还原

【Abstract】 Eu（DBM）₃Phen-doped polymer optical fibers（POFs） were prepared by thermal polymerization.The cross relaxation model of clustering Eu³+ ions was described,and the clusters in this kind of fibers were studied based on the above model.The percentages of clustering ions in different fibers were obtained by the rate equation combining with fiber transmission experiment.While concentrations in these fibers are 0.1 wt.-%,0.2 wt.-%,0.3 wt.-%,0.4 wt.-%,0.5 wt.-% and 1 wt.-%,the percentages of clustering ions are 0.045,0.07,0.07,0.07,0.07 and 0.08,respectively.The result shows that this kind of fibers has low percentage of clustering ions.With the increasing of Eu³+ concentration,the percentage of clustering ions almost not increases,the clustering of Eu³+ ions is not obvious.更多还原
