纳米金刚石中负电荷氮空位中心的荧光可以应用于量子计量、纳米传感器和生物成像，与纳米技术和生物传感领域密切相关。然而，低的色心含量和光子的收集效率是关键问题。虽然已经提出了一些关于将纳米金刚石耦合到光波导中的研究，但寻找最合适的物质和最简单、最有效的方法是关键。在这项研究中，我们提出了一种新颖的非传统方法，将负电荷氮空位含量增加到75.48%的纳米金刚石掺入碲锗酸盐玻璃中。杂化玻璃结构稳定，以teo4三角双棱锥为主。同时，复合材料增强了荧光强度。这种坚固的纳米金刚石在碲锗酸盐玻璃光学系统中具有应用于纳米粒子传感和量子计量的潜力。
Fluorescence of negative‐charged nitrogen‐vacancy centers in nanodiamond allows applications in quantum metrology, nanoscale sensor, and bioimaging, of utmost relevance to domains from nanotechnologies to biosensing. However, the low color center content and collection efficiency of photons are crucial issues. Although, several studies about coupling nanodiamond into optical waveguides have already been proposed, the search for the most appropriate substance and simplest, most effective method are of keys. In this study, we present a novel nontraditional way to incorporate nanodiamond with increased negative‐charged nitrogen‐vacancy content to 75.48% into tellurite germanate glass. The hybrid glass is stable in structure with predominant TeO4trigonal bipyramid. Moreover, the fluorescence intensity is enhanced in composite. Such robust nanodiamond in tellurite germanate glass optical system has the potential to be used for nanoparticle sensing and quantum metrology.
