Abstract
The present disclosure illustrates a composition of a visible light and infrared light transmitting optical colored glass. The chalcogenide semiconductor compound Cu2ZnSnS4 or Cu2ZnSnSe4 is added in the silicate glass system composition, to adjust color and the optical property of the glass. The glass made of this composition has a characteristic of the visible light and infrared light transmitting in a wavelength of range 400 nm to 1200 nm.
