Luminescent diamond composites

Diamond is valuable material with extraordinary high thermal conductivity and transparency in a wide spectral range from UV to IR longer wavelengths. Defects impurities the diamond lattice can absorb emit light at wavelengths specific for each of such “color centers.” Particularly, vacancy-related defects diamond, as nitrogen-vacancy (NV) or silicon-vacancy (SiV) centers, are actively investigated due their potential biomedicine, quantum optics, local thermometry magnetometry. Although great variety different color centers discovered, only limited number those point be reliably reproduced synthetic obtained either by chemical vapor deposition (CVD) high-pressure high-temperature (HPHT). An alternative approach producing luminescent diamond-based materials integrate stable non-diamond sources luminescence form nano- microparticles foreign into pristine diamond. The produced composites possess excellent properties combined optical emission characteristics, which cannot provided intrinsic good candidates well-investigated fluorides oxides doped rare-earth elements (RE) other chalcogenides sulfides, selenides tellurides. Here we briefly review recent achievements fabrication these new diamond-RE composites, compare them outline prospects applications photonics, markers, monitors high-power synchrotron, X-ray beams lasers.
