The silver-plated layer has very active chemical reactivity in the light, and it is easy for silver-plated layer to produce chemical reaction with external sulfides, causing the surface of the silver-plated layer to corrode and accelerate the discoloration. Light is an additional energy source that promotes the ionization of metallic silver. Related studies have shown that the wavelength and time of irradiation. Light is an additional energy source that promotes the ionization of metallic silver. Relevant researches show that the wavelength and time of the irradiation light have a great effect on the discoloration of the silver coating.
