| Outline of Final Research Achievements |
Coloring mechanisms on glass are used by XAFS and computer simulations. From XAFS measurement of metal ions Fe ion is 3, Mn is mixture of 2 and 3 and Co is 4. Pb state is PbO. Pb concentration do not relate to oxidation number. First principle calculation is used combine between CoO2 and SiO2. Absorption of visible light is not at combine of CoO2 and SiO2. Co structure is important.
