    (2019) BOZ,İbrahim; GÖKTAŞ,Abdullah; TUMBUL,Ahmet; KILIÇ,Ahmet; 17.02. Department of Electricity and Energy / Elektrik ve Enerji Bölümü; 17. Vocational Higher School / Meslek Yüksekokulu; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
    Chemically derived polycrystalline ZnS thin films have a profound potantial for the optoelectronic and luminescent devices. Regarding this crucial fact that the chemically grown ZnS thin films, prepared at different Zn and S molar ratios, was investigated by X-ray diffraction (XRD), photoluminescence (PL), Fourier transmission infrared (FT-IR) spectrocopy and UV-Vis spectrocopy. The obtained results showed that the ZnS thin films had a hexagonal crystall structure. The crystalline quality of the films was changed depend on the molar ratios. The FT-IR analysis confirmed the formation of Zn-S binding. The PL measurements verified the presence of the main PL emissions of the ZnS structure. The UV-Vis analysis showed the transmittance and absorbance intensity was changed according to the molar ratios as well as the optical band gap of the ZnS thin films
