The present invention relates to an alkali borosilicate glass in which the total iron content in terms of Fe2O3 in the alkali borosilicate glass is 0.03% or more in mol% on the basis of oxides, the ratio of tricoordinated boron to the total amount of tricoordinated boron and tetracoordinated boron is 61% or less, the alkali borosilicate glass does not substantially contain Se and CoO, and the thickness of the alkali borosilicate glass is 2.0 mm when converted to a thickness of 2.0 mm. The alkali borosilicate glass has a solar transmittance Te of 90% or less as determined by ISO 9050: 2003, a dominant wavelength Dw of 520 nm or more and 574 nm or less as determined by using a standard C light source as determined by JIS Z 8701: 1999, and an excitation purity Pe of 4.0% or less as determined by using a standard C light source as determined by JIS Z 8701: 1999.

    本发明涉及一种碱硼硅酸盐玻璃,其中,以氧化物基准的摩尔%计,所述碱硼硅酸盐玻璃中的换算为Fe2O3的总铁的含量为0.03%以上,相对于三配位硼与四配位硼的合计量,三配位硼的比例为61%以下,所述碱硼硅酸盐玻璃实质上不含有Se和CoO,将厚度换算为2.0mm时,所述碱硼硅酸盐玻璃的由ISO‑9050:2003规定的太阳能透射率Te为90%以下,所述碱硼硅酸盐玻璃的使用由JIS Z 8701:1999规定的标准C光源测定的主波长Dw为520nm以上且574nm以下,并且所述碱硼硅酸盐玻璃的使用由JIS Z 8701:1999规定的标准C光源测定的激发纯度Pe为4.0%以下。
