NOT KNOWN DETAILS ABOUT FE²�?ZNS CRYSTAL

Satellite peak 1, having a binding Strength of 716.1 eV, delivers very clear proof for that existence of Fe2+. Satellite peak 2, which has a binding energy of 720.1 eV, may be assigned into the attribute peaks of Fe3+; its peak intensity may be very weak in comparison with satellite peak 1, which signifies that the amount of Fe3+ is amazingly compa
