Photoluminescence properties of a single tapered CuO nanowire

Formation of CuO nanorods and their bundles by an electrochemical dissolution and deposition process

“…12 shows photoluminescence (PL) spectra for the asdeposited and annealed (at 500 • C for 3 h) samples. Emission peaks at 350 nm (3.55 eV), 410 nm (3.03 eV), 473 nm (2.62 eV) and 518 nm (2.40 eV) were observed in all samples, which indicated CuO emission [9,12,[28][29][30][31][32][33]. It is noted that the peak centered at 430 nm (2.89 eV), which indicates Cu emission, did not appear in the annealed sample [11].…”

Study of structural and optical properties of cupric oxide nanoparticles

“…Nanocrystalline semiconductor particles have drawn considerable interest in recent years due to their interactive properties such as large surface-to-volume ratio and distinctive electronic and optical properties as compared to bulk materials (Huang et al 2010;Son et al 2009;Xu et al 2007;Lim et al 2012;Qi et al 2007;Kidowaki et al 2012). Cupric oxide (CuO) is a transition metal oxide.…”

Copper (II) oxide nanowires for p-type conductometric NH3 sensing

“…Among the different techniques to synthesize CuO nanowires, such as electro-spinning [17] and template-assisted growth [11], the direct oxidation of Cu foils [14][15][16] is easy to implement and scalable, providing pleasing results in terms of crystallinity and material quality [14]. These facts are triggering the research on one-dimensional (1D) CuO nanostructures [5,12,13,15,16], but the scope of their sensing characteristics remains uncompleted according to the authors' best knowledge since the studies performed with individual CuO nanowires have been limited up to now [12,13,15].…”
