Bu çalışmada, Zn (O,OH,S) filmleri ZnO gövde tabaka üzerine 500 °C’de tavlanarak sentezlenmiştir. Filmlerin yapısal özellikleri, yüzey morfolojileri ve detaylı optik özellikleri üzerindeki değişimler tavlama süresine bağlı olarak incelenmiştir.(30 dk. ile 90 dk. aralığında).30 ve 90 dk. tavlanan örnekler bozunmuş morfoloji sergilerken, 60 dk. tavlanmış örnekler farklı boyutlarda nano-çiçek oluşumlar sergilemiştir. Tüm filmler ZnO-hekzagonal yapısı göstermesine karşın, en belirgin ZnS-ile ilişkili pikler 90 dk. tavlanmış örneklerde görülmüştür. Uv-Vis spektrumu ile optik band sınırının 362 nm.ye kaydığı tespit edilmiştir. ZnO, Zn(OH)2 titreşim pikleri çok keskin olmasına karşın, ZnS titreşim pikleri çok zayıftır. PL şiddetleri tavlama zamanı ile değişkenlik göstemiştir fakat tüm filmler için kusur-seviyeleri ile ilişkili pikler benzerdir. 

In this study, Zn (O,OH,S) films were synthesized onto ZnO seed layersby chemical bath deposition, annealed at 500 °C. The differences of structural, morphological and detailed optical properties of the films were investigated depending on the annealing time (between 30 min. and 90 min.). While samples of 30.min and 90 min. showed decomposed structures, sample of 60 min. showed different dimensions of nano-flower structures. Although all films have ZnO-hexzagonal crystal structure, the most obvious ZnS-related peaks were observed in sample of 90 min. Optical absorption edge is shifted at 362 nm from Uv-Vis spectroscopy. Although ZnO, Zn(OH)2 vibration related peaks are so sharp, ZnS vibration peaks are so weak for all samples from FTIR. The PL intensities are differential with the annealing time but defect state-corresponding peaks are similar for each films.
