In this study, colored glass was prepared using layer coating with silver nanostructures such as nanowire, spherical nanoparticles and dendritic. Silver nanowires were prepared by a solvo-thermal and polyol combination method with different molar ratios of poly-vinyl-pyrrolidone and silver nanoparticles by polyol and chemical reduction methods. The silver dendritic nanostructure was made by dip coating method in different sizes. Characterization of silver nanostructures was accomplished by X-ray diffraction, scanning electron microscopy and ultraviolet-visible spectroscopy. The cleaned glasses then were coated by immersion in a solution of silver nanostructures. In order to fix the color of the glasses after the coating operation, the glasses were heated at 700 °C. The colors of the glasses were in the yellow color range. The glass color characteristics, including the color parameters and color coefficients and the dominant wavelength, were studied using a spectrophotometer and color triangle. It was observed that the color coefficients (L*a*b*) for the same concentrations and different morphologies of the nanostructures were different and varied from (55.87, -8.39 and 9.94) for nanowires to (-66.85, -20.65 and 18.91) for dendritic and (46.69, -1.65 and -30.62) for nanoparticles. The effect of the concentration and size of nanostructures on the color of the glasses was also investigated.
