X-ray Control of the Color Centers Charge State in Crystals

This master's thesis is devoted to the study of the X-ray radiation effect on colour centres in diamonds and the control of their charge state using this radiation. This work is divided into two chapters. The first chapter describes the basic concepts and theories used in this work, such as Fourier transform, -spectroscopy, -spectrometer, the interaction of infrared radiation with matter, the concept of colour centres and X-rays. The second chapter describes the samples, the experimental setup and the main equipment, the development of a special attachment for exposure to X-ray radiation, the experimental data obtained in the work, and the work's conclusions. In the course of this work, it was revealed that colour centres change under the influence of X-ray radiation, which shows that control of the charge states of the centres is possible. We also performed calculations of the concentration of SiV defects.
