1) cooperative up conversion
合作上转换
1.
It is shown that the cooperative up conversion processes of Yb 3+ →Tm 3+ energy transfer is responsible for the fluorescence quenching at high Yb 3+ doping level.
研究了ＹｂＹＡＧ晶体的光谱特性，通过不同掺杂浓度的ＹｂＹＡＧ晶体的荧光寿命的测定，确定了Ｙｂ３＋在ＹｂＹＡＧ晶体中的最佳掺杂浓度，用合作上转换机制解释了高浓度掺杂时的荧光浓度猝灭效应，研究了掺杂原子分数为０。
2) cooperative up-conversion coefficient
合作上转换系数
3) up-conversion cooperative radiation fluorescence
上转换合作辐射荧光
4) energy transfer via cooperative upconversion
协作上转换能量转移
1.
It is found that fluorescence intensity decreases evidently with increasing erbium-doping concentration under higher doping, and it is mainly a result of concentration quenching effect in which energy migration takes place due to energy transfer via cooperative upconversion between Er~ 3+ ions when the procedure of removing OH~ -1 by bubbling oxygen is adopted in melting glass.
通过对测量到的归一化荧光强度衰减曲线的拟合,进一步得到了协作上转换能量转移系数CTZN=3。

补充资料：可转换证券的转换价值
可转换证券的转换价值——
如果一种可转换证券可以立即转让，它可转换的普通股票的市场价格与转换比率的乘积就是可转换证券的转换价值，即转换价值等于普通股票的市价乘以转换比率。
