Decay rate enhancement of diamond NV-centers on diamond thin films

Decay rate enhancement of diamond NV-centers on diamond thin films
Decay rate enhancement of diamond NV-centers on diamond thin films
We demonstrate experimentally two-fold enhancement of the decay rate of NV0
centers on diamond/Si substrate as opposed to a bare Si substrate. We link the decay
enhancement to the interplay between the excitation of substrate modes and the presence of non-radiative decay channels. We show that the radiative decay rate can vary by up to 90% depending on the thickness of the diamond film.

Abstract

We demonstrate experimentally two-fold enhancement of the decay rate of NV0
centers on diamond/Si substrate as opposed to a bare Si substrate. We link the decay
enhancement to the interplay between the excitation of substrate modes and the presence of non-radiative decay channels. We show that the radiative decay rate can vary by up to 90% depending on the thickness of the diamond film.
