چکیده انگلیسی
Thin films of Cd1âxMnxS (0â¤xâ¤0.5) were formed on glass substrates by resistive vacuum thermal evaporation. All the films were deposited at 300 K and the films were annealed at 373, 473 and 573 K for 1 h in a vacuum of 10â6 mbar. Atomic force microscopy (AFM) studies showed that all the films investigated were in nano-crystalline form with a grain size in the range 36-82 nm. All the films exhibited a wurtzite structure of the host material. The lattice parameters varied linearly with composition following Vegard's law in the entire composition range. Photoluminescence studies showed that two distinct emission bands were observed for each Cd1âxMnxS compound. One corresponds to internal transition and the other one is due to the transition of Mn2+ ions in interstitial sites or in small 'Mn' chalcogenic clusters.
