“…The ODMR signals were simultaneously imaged from all fluorescent diamond spots over the entire FOV of the objective in one exposure shot. Such wide-field imaging is faster and more efficient than confocal scanning using an NV probe on an AFM 24 , which typically requires hours of measurement time to scan the entire sample area.…”

Magnetometry with nitrogen-vacancy (NV) color centers in diamond has gained significant interest among researchers in recent years. Absolute knowledge of the three-dimensional orientation of the magnetic field is necessary for many applications. Conventional magnetometry measurements are usually performed with NV ensembles in a bulk diamond with a thin NV layer or a scanning probe in the form of a diamond tip, which requires a smooth sample surface and proximity of the probing device, often limiting the sensing capabilities. Our approach is to use micro- and nano-diamonds for wide-field detection and mapping of the magnetic field. In this study, we show that NV color centers in randomly oriented submicrometer-sized diamond powder deposited in a thin layer on a planar surface can be used to detect the magnetic field. Our work can be extended to irregular surfaces, which shows a promising path for nanodiamond-based photonic sensors.

Magnetometry with nitrogen-vacancy color centers in diamond has gained significant interest among researchers in recent years. Absolute knowledge of the three-dimensional orientation of the magnetic field is necessary for many applications. Conventional magnetometry measurements are usually performed with NV ensembles in a bulk diamond with a thin NV layer or a scanning probe in the form of a diamond tip, which requires a smooth sample surface and proximity of the probing device, often limiting the sensing capabilities. Here, we present a method for determining the threedimensional orientation of the magnetic field vector relative to the diamond crystal lattice. We demonstrate that NV centers in arbitrarily oriented submicrometer-sized diamond powder deposited on a planar surface can be used for sensing the magnetic field. Our work can be extended to irregular surfaces, which shows a promising path for nanodiamond-based photonic sensors.

“…Previously, NV centers have been prepared on various semiconductor and insulating substrates in the form of cantilevers 16 , microcavities 17 , and polymer membranes 18 . Such HNQ devices fabricated on diamonds and silicon surfaces have the advantages of being lightweight, and highly responsive to changes in the local environment.…”

The quantum properties of fluorescent nanodiamonds offer great promise for fabricating quantum-enabled devices for physical applications. However, the nanodiamonds need to be suitably combined with a substrate to exploit their properties. Here, we show that ultrathin and flexible glass (thickness 30 microns) can be functionalized by nanodiamonds and nano-shaped using intense femtosecond pulses to design cantilever-based nanomechanical hybrid quantum sensors. Thus fabricated ultrathin glass cantilevers show stable optical, electronic, and magnetic properties of nitrogen-vacancy centers including well-defined fluorescence with zero-phonon lines and optically detected magnetic resonance (ODMR) near 2.87 GHz. We demonstrate several sensing applications of the ultrathin glass cantilever by measuring acoustic pulses, external magnetic field, or CW laser-induced heating by measuring Zeeman splitting and thermal shifting of ODMR lines. This work demonstrates the suitability of the femtosecond-processed ultrathin glass as a new versatile substrate for multifunctional quantum devices.
