纳米金刚石中带负电荷的氮空位色心的荧光被应用于纳米传感。本文采用溶胶-凝胶法和旋涂法在硅溶胶中引入分散良好的纳米金刚石，制备了稳定透明的ND-SiO2复合薄膜。透射电子显微镜、X射线衍射和拉曼光谱都表明纳米金刚石颗粒在二氧化硅薄膜中均匀分散。通过研究从液氮温度到室温的荧光行为，发现杂化涂层具有明显的温度依赖性。随着温度的升高，零声子线位置红移、强度降低、半峰全宽延长、振幅减小是其明显的特征。此外，灵敏度在80 K时为19 K Hz−1/2，而在300 K时增加到28 K Hz−1/2。
Fluorescence of negatively charged nitrogen-vacancy color centers in nanodiamond is applied in nanoscale sensing. Here, we generated a stable transparent composite ND-SiO2film by introducing well-dispersed nanodiamonds into silica sol with sol-gel method and spin coating. The transmission electron microscope, X-ray diffraction and Raman curves all can demonstrate homogeneous dispersion of nanodiamond particles in the silicon dioxide film. The hybrid coating displayed significant temperature dependence by studying the fluorescence behavior from liquid nitrogen temperature to room temperature. With rising temperature, the red shift in zero phonon line position, reduction in intensity, extension in the full width at half maximum and decrease in amplitude were obviously typical characteristics. In addition, the sensitivity was 19 K Hz−1/2at 80K, while it increased to 28 K Hz−1/2at 300K.
