Evanescent wave interaction with nanoparticles on optical fiber modulate side emission of germicidal ultraviolet light

Silica nanoparticle coating on quartz optical fiber facilitates side-emission of germicidal ultraviolet light (UV-C), which shows promise for disinfection of contaminated air, water, and surfaces. However, the emitted light along...

Carbon nanotube cathodes covered on the cylindrical surface of a fiber

Carbon nanotube (CNT) arrays were synthesized on the cylindrical waveguide surface of a quartz optical fiber by chemical vapor deposition (CVD) to serve as field emission cathodes.

Preparation and Thermodynamics of Nickel-Phosphor Deposition on Surface of Quartz Optical Fiber by Electroless Plating

The electroless nickel-phosphor deposition on quartz optical fiber surface was carried out by single factor test. The optimum NiSO4·6H2O, NaH2PO2·H2O , C3H6O2 and H3BO3 concentrations, pH value and temperature were determined to be: 0.1331 mol/L, 0.3019 mol/L, C3H6O20.3761 mol/L, H3BO3 0.4520 mol/L, 4.5 and 84°C, respectively. Scanning electron microscope, stereomicroscope and thermal shock rest were applied to measure the morphology and strength of adhesion of the deposited Ni-P coating. The result showed that a desired Ni-P coating with good smoothness and adhesion was prepared under the optimal conditions. The thermodynamic models were established and proven by the current study.
