INFLUENCE OF SULFUR CONCENTRATIONS ON THE OPTICAL PROPERTIES OF ZnS FILMS ONTO ZnO SEED LAYER SYNTHESIZED BY CHEMICAL BATH DEPOSITION
Abstract
ZnS films were synthesized onto ZnO seed layer by chemical bath deposition (CBD) and annealing at 500ºC. To prepare films, molar percentages of sulfur were chosen as 6, 7, and 8%. Working temperatures of ZnO seed layer and ZnS films were 50 ± 5 and 70 ± 5ºC, respectively. Differences in structural, optical, and morphological properties were measure on those films. EDX analysis shows that S:7% films had the maximum elemental sulfur ratio. All films have ZnS (hexzagonal) [110] preferential orientation with different FWHMs. The most obvious nanorod formations were observed in S:7% films. Additionally, S:6% films had higher optical transparency over 65% in the visible region. Photoluminescence spectrum showed that the broad blue and narrow green emission and intensity were changed upon sulfur inclusion.
