Abstract: Spontaneous-emission enhancement in a Tamm plasmon microcavity with an active region with organic material 4.4'-bis( $N$-carbazolyl)-1.1'-biphenyl (CBP) is theoretically and experimentally studied. The microcavity consisted of a Bragg reflector made of silicon oxide and tantalum oxide, over which CBP and silver layers are applied. The dependences of the Purcell modal factor on the emission direction and frequency, as well as the Purcell factor spectrum are calculated. The emission and fluorescence decay spectra in time are measured in the ultraviolet range. It is found that the probability of spontaneous emission increases and the maximum Purcell factor reaches three at frequencies corresponding to eigenmodes of the Tamm plasmon.

Keywords: Tamm Plasmon (TPs), Spontaneous Emission Enhancement, Organic Active Region, Purcell Factor, Tantalum Oxide.
