Sapphire Fiber

The feasibility of sapphire fiber sensors based on evanescent absorption spectroscopy in the infrared range for determination of water content in polar organic solvents has been investigated. Evanescent absorption spectra of sapphire fiber sensors in glycerol, ethanol and glycol with different volume concentrations were recorded and analyzed, respectively. Evanescent absorbance around 2.7μm of fiber sensors in those organic solvents has been utilized to implement for in situ monitoring water concentration in organic solvents. The evanescent fiber sensors for monitoring water concentrations in those organic solvents are acceptably accurate, cost-effective and reliable. Overall results demonstrate that the sapphire fiber sensor based on evanescent absorption is a promising candidate for prediction of water content in polar organic solvents in on-line and remote situation.

Fluorescent Material

A novel bi-Schiff-base Zn (II) complex, 1-acetyl-2-naphthol-4, 4’-diaminodiphenylmethane Zn (II), has been synthesized. The luminescent characterizations of the Zn (II) complex material have been studied in solid state and in organic solvents, and the effect of Mg (II) ion on the fluorescence of Zn (II) complex has also been investigated in organic solvents. The results show that the Zn (II) complex material emits weak green fluorescence at 536 nm in solid, emits strong blue fluorescence 451 nm in DMSO. However, there do have luminescent emissions in methanol and in ethanol duo to the influence of overtones.
