Abstract

The invention is applicable to the technical field of color center diamond preparation and provides a color center diamond preparation method and a color center diamond. The method comprises the following steps: cutting any shortest side of a cuboid diamond along a length direction of the shortest side of the cuboid diamond so as to form a concave arc-shaped cut section; treating the cut diamond to form a color center; and plating surfaces except the concave arc-shaped cut section of the diamond with the color center by a composite membrane, wherein the composite membrane comprises a high-reflection plating layer. Laser enters from the concave arc-shaped cut section, so that the optical path length of the laser can be increased. Meanwhile, the composite membrane has a high reflection rate,the laser and fluorescent light can be prevented from being refracted outside the diamond, so that the fluorescent light collection rate and the laser emission efficiency can be improved.

Description

technical field [0001] The invention belongs to the technical field of color center diamond preparation, and in particular relates to a color center diamond preparation method and color center diamond. Background technique [0002] Diamond nitrogen-vacancy (Nitrogen-Vacancy, NV) color centers have stable optical properties, can emit fluorescence, and have unique advantages such as electron spin characteristics and ideal solid-state qubits, making diamond NV color centers in quantum technology and biology. Imaging and other fields have been widely used. [0003] The traditional method of exciting the diamond NV color center is to use a 532nm laser to enter the interior of the diamond from the front vertically. This method will result in a short laser optical path, generally at the μm level, which will affect the fluorescence intensity of the diamond NV color center, and the laser excitation efficiency will be low. The improved method is to enter the laser into the diamond fr...
