Decay rate enhancement of quantum emitters using nanostructures have been widely studied in the last decades, thanks to the development of science and technology of light-matter interaction in nanoscales. Hyperbolic metamaterials (HMMs) as artificial nanostructures providing high photonic density of states (PDOS) are highly promising in this regard. In the present paper, we investigate PDOS of a hyperbolic metamaterial component consisting of 6 alternating gold-alumina layers, using FDTD simulation and the Green's function. Non-radiative and radiative (fluorescence) spontaneous decay rate enhancement of a quantum emitter nearby the structure is calculated. The results indicate the fluorescence enhancement of a factor of 10 having quantum efficiency of about 50 percent.
