Keywords:
bi-color spinel,optical absorption spectrum,photoluminescence spectrum
Optical absorption and photoluminescence were evaluated using FZ grown Mn doped bicolor spinel. Mn doped bicolor spinel crystals were grown using a FZ technique with changing oxygen concentration of the ambient atmosphere during the crystal growth process. Color pf the crystals change with oxygen concentrations of the atmosphere.
