Yb^（3＋）掺杂固体中的浓度猝灭机制

Concentration Quenching Mechanism in Yb￣(3+) Doped Solids

从理论上分析了在Ｙｂ３＋掺杂的各种固体中存在着浓度猝灭效应的现象，指出“合作上转换”是这种现象的起因，并与实验进行了比较．

Recently, many experiments demonstrate that there are concentration quenching effects in Yb3+ doped solids. This paper reports a theoretical analyse, of this phenomenon. It is shown that 'cooperative up conversion luminescence' is responsible for the quenching of the luminescence of Yb3+ in solids. A comparison with the experiments is given.
