摘要	In this paper, Ag, PMMA and perovskite CsPbBr3 films have been integrated into a plane waveguides to explore the optical physical mechanism and new application of plasmon structure. It is shown that the localized field on the Ag/perovskite CsPbBr3 interface has been increased giving rise to PL and radiative ratio(=-1) enhancement of CsPbBr3 excitons as varying system structures, especially modifying the thickness of PMMA. Decay curves have been fitted by both two exponential and ensemble stretched functions, respectively. It is found that there is big fitting discrepancy. Without considering the localized field enhancement on the Ag/CsPbBr3 interface, the fit results(avg, 30~25 ns) by two exponential form are similar to the results in free space reported previously. The PL lifetime shortening(avg, 12~9 ns), or radiative rate increasing have been found by the latter fitting. The above-mentioned investigations can provide the basis for optical physical fundamental research and design and developing of surface plasmon polaritons(SPPs) luminescence-display devices. 2021, Science Press.
