Surface plasmon polariton (SPP) is a kind of electromagnetic oscillation coupling due to the undulation of charge intensity, which is excited at the interface between metal and dielectric. With the help of near-field enhancement, surface plasmon polariton plays an important role in nano-photonics. When the effect of SPP is used to fabricate the single photon resource, not only the volume can be miniaturized, but also the single photon radiation and collection efficiency can be effectively improved. According to the relationship between the factor of Purcell effect and the density of states, we calculate the local density of electromagnetic states(LDOS) and Purcell factor. By analyzing the local densities of electromagnetic states of different metallic materials, we find that silver is the most suitable metal. For a certain metal, the detection distance and the dielectric material also have influences on local density of electromagnetic states and Purcell factor, and they provide important parameters for the designing of single photon resource based on surface plasmon resonances.
