| 1 | Ultra-high-resolution detection of Pb2+ ions using a black phosphorus functionalized microfiber coil resonator显示文摘A black phosphorus(BP) functionalized optical fiber sensor based on a microfiber coil resonator(MCR) for Pb^2+ ion detection in an aquatic environment is presented and experimentally demonstrated. The MCR-BP sensor is manufactured by winding a tapered microfiber on a hollow rod composed of a low-refractive-index polycarbonate(PC) resin with the BP deposited on the internal wall of the rod. Based on the propagation properties of the MCR, the chemical interaction between the Pb^2+ ions and the BP alters the refractive index of the ambient environment and thus results in a detectable shift in the transmission spectrum. The resonance wavelength moves towards longer wavelengths with an increasing concentration of Pb^2+ ions, and the sensor has an ultra-high detection resolution of 0.0285 ppb(parts per billion). The temperature dependence is 106.95 pm/°C due to the strong thermo-optic and thermal-expansion effect of the low-refractive-index PC resin. In addition, the sensor shows good stability over a period of 15 days. The local pH also influences the sensor, with the resonance wavelength shift increasing as pH approaches a value of 7 but then decreasing as the pH value increases further due to the effect of the BP layer by H^+ and OH-ions. The sensor shows the potential for high-resolution detection of Pb^2+ ions in a liquid environment with the particular advantages of having a simple structure, ease of fabrication,low cost, low loss, and simple interrogation. | YU YIN SHI LI SHUNBIN WANG SHIJIE JIA JING REN GERALD FARRELL ELFED LEWIS PENGFEI WANG | 2019 | Photonics Research2019，7，6： | 2 |
