Characterization of Glasses by Ion-Exchange (III) : Behavior of Optical Properties

ABSTRACT

The behavior of optical properties of ion exchanged glasses was investigated inthis study. The used glasses were soda-lime-silica glasses that were produced by float process. The coloring effect by Ag colloids is measrued by spectral transmittance, color coordinates, dominant wavelength and excitation purity resulting from silver ions exchange of glasses immersed into the mixed molten salt with AgNO3. Ion exchange coloring of glasses made it possible to obtain glasses with a range from yellow to brown, and transmittance was decreased with increasing the amount of Ag colloids which reduced from Ag+ions. Also, obtain from yellow to reddish brown with increasing purity by reheating treatment in air for ion exchanged glasses. The size of Ag colloids are 0.02~0.1${mu}{textrm}{m}$ with ion exchange conditions.
