Abstract
Zn1-xMnxSe Diluted magnetic semiconducting films with x = 0.00, 0.10, 0.15 and 0.20 were formed at 523 K on glass substrates by co-evaporation. X-ray diffraction studies revealed that the films were polycrystalline in nature with zinc blende structure with preferential orientation along (111). Optical transmittance studies indicated a nonlinear variation of band gap with ‘x’ exhibiting a downward bowing at lower concentrations. All the films showed photoluminescence with composition dependent intensities and emission wavelengths.
