Abstract

Copper oxide nanoparticles (CuO NPs) were synthesized at 105 °C via a hydrothermal deposition technique. The CuO nanoparticle structure was characterized via X-ray diffraction (XRD) and scanning electron microscopy (SEM). The optical properties of the nanoparticles were examined via a UV‒vis spectrophotometer. For all the nanoparticles, the XRD measurements revealed the monoclinic CuO phase. The direct optical band and Urbach gap width of the nanoparticles were 2.88 eV and 0.44 eV, respectively. On the basis of optical measurements, optical parameters such as the refractive index (n), extinction coefficient (k), and real (ε1) and imaginary (ε2) components of the dielectric constant were calculated. At a wavelength of 550 nm, the optical constants n and k were found to be 2.75 and 0.00024, respectively, corresponding to dielectric real and imaginary constants of 7.570 and 0.0013. Additionally, photon interactions with CuO NPs at various energy levels were simulated via the FLUKA program. The energy deposition in the material provided valuable information for assessing the radiation shielding capabilities of the investigated material.

Özet

Bakır oksit nanoparçacıkları (CuO NP), 105 °C’de hidrotermal çöktürme yöntemiyle sentezlendi. CuO nanoparçacıklarının yapısı, X-ışını kırınımı (XRD) ve taramalı elektron mikroskobu (SEM) ile karakterize edildi. Optik özellikleri ise UV-vis spektrofotometresi kullanılarak incelendi. Tüm nanoparçacıklar için XRD ölçümleri, monoklinik CuO fazının oluştuğunu ortaya koydu. Nanopartiküllerin direkt optik bant genişliği ve Urbach boşluk genişliği sırasıyla 2,88 eV ve 0,44 eV olarak bulundu. Optik ölçümlere dayanarak kırılma indisi (n), soğurma katsayısı (k) ve dielektrik sabitinin gerçek (ε1) ve sanal (ε2) bileşenleri gibi optik parametreler hesaplandı. 550 nm dalga boyunda, n ve k değerleri sırasıyla 2,75 ve 0,00024 olarak bulunurken, bu değerlere karşılık gelen ε1 ve ε2 değerleri 7,570 ve 0,0013 olarak belirlendi. Ayrıca, farklı enerji seviyelerinde fotonların CuO NP’lerle etkileşimi FLUKA programı ile simüle edildi. Malzemedeki enerji birikimi, çalışılan malzemenin radyasyon zırhlama özelliklerini değerlendirmek için önemli bilgiler sağladı.
