Abstract

The method of hot-filament chemical vapor deposition has been employed to synthesize diamond particles with germanium–vacancy and silicon–vacancy color centers. In the next stage, the reactive ion-plasma etching of the particles was performed. This, yielded diamond nanoparticles with photoluminescence spectra constituted by two narrow high-intensity zero-phonon lines of the centers introduced. These fluorescent diamond nanoparticles are promising for application as sources of double-wave narrow-band emission in luminescent nanothermometry.

同时引入锗空位和硅空位色心的基于金刚石纳米粒子的双波窄带发射源

摘要

热丝化学气相沉积法已被用于合成具有锗空位和硅空位色心的金刚石颗粒。在下一阶段，进行粒子的反应性离子等离子体蚀刻。这产生了具有由引入的中心的两条窄的高强度零声子线构成的光致发光光谱的金刚石纳米粒子。这些荧光金刚石纳米粒子有望在发光纳米温度计中用作双波窄带发射源。
