Температурные характеристики люминесцирующих центров "кремний-вакансия" в алмазных частицах, синтезированных различными методами

Abstract

Recently, we have developed a new approach to measuring local temperatures and controlled heating using diamond particles containing luminescent “silicon-vacancy” centers (SiV). Here, in the development of this approach, the two dependencies are investigated by confocal laser spectroscopy. First, spectral characteristics of SiV-centers in diamond microparticles of various synthesis on the ambient temperature are studied. Second, the heating temperatures of diamond particles on the optical power are analyzed. The maximum temperature sensitivity of SiV-luminescence is determined for diamonds obtained at high pressures, while the maximum heating efficiency is observed for diamonds synthesized by chemical vapor deposition.
