珀塞尔因子是微腔中自发发射增强的标准品质因数，并且也被提出来描述等离子体共振的发射增强。质量因子，模式的体积，和珀塞尔因子为单个和耦合等离子体球的发射率的精确计算的比较表明，一个珀塞尔因子来自质量因子和模式的体积不描述由于等离子体天线的发射变化。(C)2010年美国光学学会
The Purcell factor is the standard figure of merit for spontaneous emission enhancement in microcavities and has also been proposed to describe emission enhancements for plasmonic resonances. A comparison of quality factor, mode volume, and Purcell factor for single and coupled plasmon spheres to exact calculations of emission rates shows that a Purcell factor derived from quality factor and mode volume does not describe emission changes due to plasmon antennas.
