The dependence of radiative and nonradiative transition probability on the temperature is discussed, and the curve of concentration quench and temperature quench is given.
The concentration quenching of organic dyes is mainly induced by the organic molecular interactions, such as formation of excimer and dimer, intercrossing relaxation, etc.

在正电性纳米银上，当分子的浓度较大时观察到荧光猝灭，当分子的浓度较小时观察到荧光增强。
On PCS, the fluorescence of RhB is enhanced when the concentration is low, whilst when the concentration is high the fluorescence of RhB is quenched.
