  1. aThe average lifetimes for all films and cavities are calculated based on a three-exponential model convoluted with the instrument response function (IRF): <τ> = \(\mathop {\sum }\nolimits_i \tau _i^2B_i/(\tau _iB_i)\), where Bi is the amplitude of the corresponding component. The error bars of the average lifetimes are obtained from the deconvolution fitting of the decay.
