All‐Optical Electric Field Sensing with Nanodiamond‐Doped Polymer Thin Films

Advanced Functional Materials, EarlyView.
The photoluminescence (PL) of fluorescent nanodiamonds (FNDs) in a polymer‐based capacitor device is sensitive to electric fields. When an external electric field is applied, the PL intensity of the negatively charged nitrogen‐vacancy center (NV‐) increases, while that of the neutrally charged NV center (NV0) decreases.
