摘要: Disclosed is an optical glass which comprises a substance A and B in 100 wt% of base composition comprising at least 2-20 SiO2, 5-45 B2O3 10-29 La2O3, or B2O3, 0-45 RO [R = Zn, Sr, Ba], 0-10 Ln2O3 [Ln Y, Gd] 1-20 ZrO2+Nb2O5+TiO2+Ta2O5. The (A) can emit light having wavelength λ2 when irradiated with λ1, the λ3 wherein wavelengths have relationship represented by following formula: λ1<λ2<λ3.
