Kobalt oksit filmleri kimyasal banyo depolama yöntemiyle 95 °C banyo sıcaklığında ve 8 saat depolama süresinde camtabanlar üzerine üretilmiştir. X-ışını kırınım deseni incelendiğinde, numunenin yüzey merkezli kübik Co3O4 kristal yapısınasahip olduğu belirlenmiştir. Kübik kristal fazı nanoçubuklar şeklinde alan emisyon taramalı elektron mikroskobugörüntülerinden açıkça görülmüştür. Numunenin Raman spektrumu Co3O4 nanokristallerin varlığını desteklemektedir.Absorbans ölçümlerinden numunenin direkt bant geçişine sahip olduğu ve bant aralığı değerleri Eopt1 = 1,48 eV ve Eopt2=2,05eV olarak belirlenmiştir. Numunenin bazı optik parametreleri dalgaboyunun fonksiyonu olarak zarf eğrisi yöntemi yardımıylaincelenmiştir. Co3O4 filminin dielektrik sabitleri (n, k, ε1 ve ε∞), plazma frekansı ωp ve taşıyıcı yoğunluğu Nopt gibi optiksabitleri belirlenmiştir.

OPTICAL CONSTANTS OF Co3O4 FILM PRODUCED BY CHEMICAL BATH DEPOSITION

Öz:
Cobalt oxide films have been prepared by chemical bath deposition method on glass substrates at 95 °C bath temperature for 8 h deposition time. X-ray diffraction pattern showed that the sample has face-centered-cubic Co3O4 structure. The cubic phase is clearly seen in the form of long rods from FESEM micrographs. Raman spectrum confirmed the formation of the Co3O4 nanocrystals. The band gap of the Co3O4 film was determined using the UV-Vis-NIR absorption spectra. The sample has exhibited direct transition with the band gap values of Eopt1 = 1,48 eV and Eopt2=2,05 eV. Some optical parameters of the sample as a function of wavelength were studied by applying the envelope method. The optical constants of the Co3O4 film, such as dielectric constants, (n, k, ε1 and ε∞), plasma frequency, ωp, and carrier concentration, Nopt, were also evaluated.
