A kind of crystal implantation doping preparation method of nano-diamond transition metal color center

Abstract

The invention relates to the field of nano-diamond color centers, in particular to a preparation method for implanting and doping nano-diamond transition metal color centers, comprising the following steps: growing a nano-diamond film on the surface of a quartz substrate to form a diamond substrate, and removing surface graphite from the diamond substrate Afterwards, ultrasonic cleaning is carried out; the nano-diamond colloid solution and transition metal powder are evenly mixed to prepare a mixed crystal planting liquid; the diamond substrate is placed in the prepared mixed crystal planting liquid, and ultrasonic crystal planting is performed to obtain a diamond substrate with uniform distribution of mixed crystal seeds Re-grow a nano-diamond film on the surface of the diamond substrate after the crystal planting is completed; then perform high-temperature annealing and remove the surface graphite treatment to obtain a relatively pure diamond with a transition metal color center. The invention implants evenly distributed mixed crystal seeds on the surface of the diamond substrate by means of ultrasonic crystal planting, introduces transition metal elements into the diamond growth environment, and conveniently and efficiently realizes the preparation of nano-diamond transition metal color centers.

Description

technical field [0001] The invention relates to the field of diamond color centers, in particular to a method for preparing nano-diamond transition metal color centers by planting and doping. Background technique [0002] Diamond color centers are photostable solid-state sources of single photons at room temperature, and can be used as carriers of quantum information to complete tasks such as quantum communication or quantum computing; they also play an important role in biomarkers and nanomicroscopy. In recent years, my country's technology in the application of quantum communication technology has developed rapidly. However, there are relatively few studies on the preparation of single photon sources in my country. The single photon sources used by many research groups come from abroad. Therefore, in order to ensure the smooth development of our country in the fields of quantum information and quantum computing, it is necessary to strengthen the research on the preparati...
