| Abstract: | |
|
The structure of 30 Li2O – (10-x) ZnO -60 B2O3: x MnO glass systemwith0≤ x ≤ 0.6 mol% was prepared. The optical absorption indicates that the presence of manganese ions predominantly in Mn2+ state occupy tetrahedral positions when the concentration of MnO at about 0.4 mol %; whereas beyond 0.4 mol % the manganese ions seem to exist in Mn3+ state. |
