Luminescence induced in diamond by He+ ion implantation into SiC/C composites with an inverse opal structure

Abstract

The photoluminescence induced in diamond by helium ion implantation into SiC/C nanocom posite samples and their structure revealed by high resolution transmission electron microscopy have been investigated. It has been found that, apart from crystallites of silicon carbide, graphite, and amorphous car bon, in the structure of the composites there are spherical carbon particles containing concentric graphite like shells (onion like particles). It has been established that onion like particles are formed during high tem perature treatment of SiC/C nanocomposites in the course of their preparation. It has been shown that, after the implantation with the subsequent thermal treatment, nanocomposite samples exhibit a luminescence characteristic of N-V centers in diamonds. The assumption has been made that the diamond crystallites are formed at the center of onion like particles during high temperature treatment of the composite.

“…We have recently synthesized and studied SiC/C and C-inverse opal nanostructures with novel functional properties. [18][19][20] Further studies of the nanostructures will expand the area of their potential use and are, therefore, highly desirable. C-inverse opals (C-IOP) have a 3D ordered meso-and macroporous structure consisting of interconnected spherical pores whose size corresponds to the template particles.…”
