摘要：

Coloration and optical absorption spectra of soda-lime-silicate glass (SLS) and sodalime-borate glass (SLB) doped with MnO2 have been studied. The physical and optical properties of glass samples were investigated and compared. The results found that the refractive indices and densities of glass samples were increased along with increasing the concentration of MnO2. The colors of SLS and SLB were altered from colorless to dark purple and dark brown respectively, when increasing of MnO2 concentration. The optical absorption spectra can be confirmed the color of these glass samples. In SLS and SLB exhibited a predominant broadband peak due to Mn3+ ion around 495 nm and 470 nm respectively. This band corresponds to an allowed transition from E-5(s) -> T-5(2s) which attributed to Mn3+ ion. When increasing MnO2 concentration, the absorption banddue to Mn3+ ion was dominating.
