开发制造具有特定光学和磁性特性的色心钻石的新路线对于其在许多创新应用（例如新兴量子技术）中的应用非常重要。在这里，我们报告了一项关于从各种含锡系统高压合成金刚石的系统研究，旨在建立有利于锡原子掺入结晶金刚石并形成锡空位（Sn-V）色心的生长条件。合成实验在 6.3-7.5 GPa 和 1400-1900 摄氏度下使用三种不同类型的溶剂催化剂进行：Fe-Sn-Al、Sn-(Ti、Al、Zr) 和 Sn-Mg。我们确定了这些催化剂金刚石结晶的主要特征，并确定了合成金刚石的光致发光特性。结果发现，在研究中采用的 P-T 条件和催化剂组成范围内，Sn-Mg-C 系统是生长 Sn 掺杂单晶金刚石的最有效介质。我们表明，通过研究中开发的方法，可以制造尺寸从大约 50 μm 到大约 1mm 的金刚石单晶，其中包含具有窄零声子线的高质量 Sn-V 色心。 (C) 2018 Elsevier Ltd. 保留所有权利。
Development of new routes for fabrication of diamond containing color centers with specific optical and magnetic properties is important for its employment in many innovative applications such as the emerging quantum technologies. Here we report a systematic study on the high-pressure synthesis of diamond from various tin-containing systems aimed at establishing growth conditions favorable for the incorporation of Sn atoms in crystallized diamonds with the formation of the tin-vacancy (Sn-V) color centers. Synthesis experiments are performed at 6.3-7.5 GPa and 1400-1900 degrees C using solvent-catalysts of three different types: Fe-Sn-Al, Sn-(Ti, Al, Zr) and Sn-Mg. We established the main features of diamond crystallization from these catalysts and determined photoluminescence characteristics of the synthesized diamonds. It is found that over the range of the P-T conditions and catalyst compositions employed in the study, the Sn-Mg-C system is a most effective medium for growing Sn-doped single crystal diamond. We show that with the approach developed in the study it is possible to fabricate diamond single crystals with sizes from similar to 50 mu m to similar to 1mm containing high-quality Sn-V color centers with narrow zero-phonon lines.
