Secondly, the quenching concentration of Eu2+ and the best doped concentration of Dy3+ were affirmed by experiments and the quenching mechanism ofEu2+ was confirmed as the interaction of idol pole to idol pole on the basis of Dexter theory.

 
  • 其次研究了CaAl2Si2O8:Eu2+,Dy3+磷光体中Eu2+离子发光浓度淬灭和Dy离子最佳掺杂浓度问题,通过Dexter理论论证了Eu2+离子在磷光体中的浓度淬灭机制是电偶极一电偶极作用;
