Influence of Platinum Thin Films on the Photophysical and Quantum Properties of Near‐Surface NV Centers

open access: yesAdvanced Optical Materials, EarlyView.
This work investigates the impact of platinum thin films on shallow nitrogen‐vacancy (NV) centers in diamond for quantum sensing applications. Five samples are analyzed with varying nitrogen implantation energies (2.5–60 keV) and changes in optical properties, charge state, and coherence times are reported.
