Nanocrystalline PbS thin films produced using the chemical bath deposition method have been investigated. In all experiments, Pb NO3 2 solution and CS NH2 2 solution were used and the deposition temperature was maintained at 200C throughout the deposition. The pH value of the deposition solution is set to 11,5. Characterization of nanocrystalline PbS thin films was performed using X-ray diffraction XRD and scanning electron microscopy SEM methods. XRD results show that all films are in the cubic PbS structure. As the molarity value of the Pb NO3 2concentration increases, the thickness of the films increases. It has been observed that the thin filmin produced as Pb NO3 2 molarity 0,011 M has a higher XRD peak intensity than the other thin films produced. However, when SEM images are examined, it is observed that the thin filmin produced as 0,009 M of Pb NO3 2 molarity has less pinhole

Farklı molaritede Pb No3 2 çözeltisi kullanılarak kimyasal banyo depolaması yöntemi ile elde edilen Pbs filmlerin bazı fiziksel özellikleri

Öz

Kimyasal banyo depozisyon metot kullanılarak üretilen nanokristal PbS ince filmler incelenmiştir. Tüm deneylerde, Pb NO3 2 ve CS NH2 2 çözeltisi kullanılmıştır. Depozisyon sıcaklığı depozisyon boyunca 200C’de tutulmuştur. Depozisyon çözeltisinin pH değeri 11,5 olarak ayarlanmıştır. Nanokristal PbS ince filmlerin karakterizasyonu X-ışını kırınımı XRD ve taramalı elektron mikroskobu SEM yöntemleri kullanılarak gerçekleştirilmiştir. XRD sonuçlarına göre, tüm filmlerin kübik PbS yapısında olduğu anlaşılmıştır. Pb NO3 2 konsantrasyonunun molarite değeri arttıkça filmlerin kalınlığının arttığı gözlenmiştir. Pb NO3 2 molaritesi 0,011 M olarak üretilen ince filmin , üretilen diğer ince filmlere göre daha yüksek XRD pik şiddetine sahip olduğu gözlenmiştir. Fakat SEM görüntüleri incelendiğinde Pb NO3 2 molaritesi 0,009 M olarak üretilen ince filmin daha az pinhole sahip olduğu gözlenmiştir
