A green glass for selective absorption of the solar spectrum, which belongs to the technical field of glass production, especially in the technical field of production of colored glass, which contains about 66-75% of SiO2, about 0-5% of Al2O3, and about 3-5 of MgO. %, CaO about 6-10%, Na2O about 10-20%, K2O about 0-2%, Fe2O3 about 0.65-0.95%, FeO ratio 18-30%, TiO2 about 0.2-0.7%, CeO2 about 0.15-0.50 %, Cr2O3 is about 20-100 PPM, and Co2O3 is about 4-20 PPM. The glass illuminant D65 has a visible light transmittance of >70%, an ultraviolet transmittance of 16%, a solar transmittance of less than 41%, a dominant wavelength of 495-520 nm, and a color purity of 3-5% at a nominal thickness of 5 mm. . The invention realizes the selective absorption of the ultraviolet spectrum in the solar spectrum, can filter the harmful light in the sunlight, has low solar light transmittance, and is simpler than the production process of the existing similar products due to the characteristics of the formula composition. Reduced production costs.
