| 英文摘要 | We studied the optical properties of silica colloids suspensions made of nanospheres having an average diameter of 50, 90, 120, and 300 nm in electric field. It was illustrated that a colloidal suspension with a particle size of 120 nm shows a dramatic change of the reflection peak position in response to the applied potential. With the increase of the concentration, the position of peak maximum slightly blue-shifted and the reflection intensity slightly increased. The impact of solvents on optical properties of silica colloids suspensions was studied. It was demonstrated that the position of peak maximum has a dramatic change only in propylene carbonate; there were no marked changes in ethylene glycol and water. The intensity of reflection peak was strongest in water. We analyze the mechanism and attribute this phenomenon to the hydrogen-bonding ability of the solvents. |
