Silver nanoparticles and their application to stain glass provide a creative way for students to learn about the optical properties of silver at the nano-scale. Previous procedures obtain silver nanoparticle films, but only of a yellow color. In this work, we explored the synthesis of nanoparticle solutions and colored films, specifically of the green color. Nanoparticle solutions of a green color and partially green colored films were synthesized by combining yellow and blue nanoparticles. It was observed that homogenously colored solutions do not form homogenously colored films. Therefore, silver nanorods, which form a green solution without mixing, were synthesized in order to explore the difference in film homogeneity. The formation of these green films expands the original application of silver nanoparticles in stain glass.
