Emission of diamond NV centers in dielectric, semiconducting and plasmonic environments
Emission of diamond NV centers in dielectric, semiconducting and plasmonic environments
Nitrogen vacancy (NV) centers in diamond exhibit long coherence lifetimes at room temperature, which renders them ideal candidates for quantum information and sensing applications. The emission characteristics of NV centers demonstrate high sensitivity to a range of stimuli including electric and magnetic fields, dielectric environment, strain, temperature. However, this sensitivity also leads to a strong variation of the emission properties of NV centers in different environments, which complicates the interpretation of experimental observations. Here, we demonstrate that decay rates of NV0 centers in diamond nanoparticles strongly depend on the dielectric environment. Embedding into and placing on dielectric, semiconductor and plasmonic films of subwavelength thickness is investigated by time resolved cathodoluminescence. We also demonstrate that varying the thickness of the thin film can be employed to tune the NV0 center lifetime, as well as the ratio between radiative and non-radiative decay rate.
Our results present a simple route towards tuning the emission of NV0 centers and provide insights into the role of the dielectric environment in the radiative and non-radiative relaxation mechanism of such emitters.

Abstract
Nitrogen vacancy (NV) centers in diamond exhibit long coherence lifetimes at room temperature, which renders them ideal candidates for quantum information and sensing applications. The emission characteristics of NV centers demonstrate high sensitivity to a range of stimuli including electric and magnetic fields, dielectric environment, strain, temperature. However, this sensitivity also leads to a strong variation of the emission properties of NV centers in different environments, which complicates the interpretation of experimental observations. Here, we demonstrate that decay rates of NV0 centers in diamond nanoparticles strongly depend on the dielectric environment. Embedding into and placing on dielectric, semiconductor and plasmonic films of subwavelength thickness is investigated by time resolved cathodoluminescence. We also demonstrate that varying the thickness of the thin film can be employed to tune the NV0 center lifetime, as well as the ratio between radiative and non-radiative decay rate.
Our results present a simple route towards tuning the emission of NV0 centers and provide insights into the role of the dielectric environment in the radiative and non-radiative relaxation mechanism of such emitters.
