Bu çalışmada, sprey piroliz yöntemi ile farklı molar oranlarda (%0, 0.2, 0.5, 1, ve 2) bor katkılı ZnO nanoparçacıkları elde edilmiştir. Katkısız ve katkılı ZnO nanoparçacıklarının karakterizasyonu, X-ışını kırınımı (XRD) tekniği, yüzey morfolojisi Taramalı Elektron Mikroskobu (SEM) ve optik özellikler ultraviyole-görünür bölge spektrumu ölçülerek yapılmıştır. XRD analiz sonuçları, wurtzite kristal yapıda ZnO nanoparçacıklarının elde edildiğini göstermektedir. Bant aralığı enerjisi (Eg) her bir numune için 2.98 –3.15 eV aralığında bulunmuş ve katkı maddelerinin bant enerjisini artırdığı gözlemlenmiştir. Ayrıca 10 metal ve oksijen atomundan oluşan küme yapıları yarı deneysel/pm6 yöntemi ile optimize edilmiş, kuramsal band boşluğu enerjisi hesaplanmıştır.
In this study, ZnO nanoparticles contributed to bor in different molar rates (%0, 0.2, 0.5, 1, and 2) were obtained by the spray pyrolysis method. The characterization of the non-contributed and contributed ZnO nanoparticles, X-ray breakdown (XRD) technique, surface morphology scanned electron microscope (SEM) and optical characteristics are made by measuring the ultraviolet-visible area spectrum. The results of the XRD analysis show that ZnO nanoparticles are obtained in the wurtzite crystal structure. The band range energy (Eg) was found in the 2.98 -3.15 eV range for each sample and the additives were observed to increase the band energy. Also, the theoretical band gap energy is calculated, optimized by the semi-experimental/pm6 method of the 10 metal and oxygen atoms.
In this study, boron doped ZnO nanoparticles in different molar ratios (% 0, 0.2, 0.5, 1, and 2) were obtained by spray pyrolysis method. Characterization of pure and doped ZnO nanoparticles was performed by X-ray diffraction (XRD) technique, Scanning Electron Microscopy (SEM) and UV-vis region spectrum. XRD analysis results show that ZnO nanoparticles in wurtzite crystal structure were obtained. The band gap energy (Eg) was found in the range of 2.98 - 3.14 eV for each sample, and it was observed that the additives increased the band energy. In addition, cluster structures consisting of 10 metal and oxygen atoms were optimized by the quasi-experimental/pm6 method, and the theoretical band gap energy was calculated.
