“…The presence of Cd-O bonds were appeared at: (524.6, 540.1, 597.9, 717.5, and 856.4) cm−1 was confirmed by FTIR spectrum. This is comfortable with other researchers ( Balamurugan et al, 2016;Anitha et al,2017;Nasrullah et al, 2020;Abd et al,2020) Procedure 2: The band at 3595.3 cm-10, (Figure 5) is assigned to the OH stretching vibrations of hydroxyl groups (Selvam et al, 2020). The organic material which found at 1384.9 cm-10 (Figure 5) was attributed to C-H bending vibrations.…”

This study was identifying the flavonoids in Urtica dioica and using this extract to phytosynthesis of Cadmium oxides nanoparticles: CdO, CdO 2 with characterization about them. The results obtained from the HPLC analysis found nine compounds, which included: Rutin 26.14 % was most abundant, followed by Chlorogenic acid 22.2 %, Naringin, Meyrecetin, Quercetin, Kaempferol, Vanallic acid, Ellagic acid and Isorhamantin.Two procedures were used to phytosynthesis NPs. The results showed that their average size (calculated by AFM) were: (75.25 and 70.34) nm for procedure1and procedure 2, respectively. From SEM study, there were nanorods particles produced by procedure 1 with dimensions range less than 50 nm, in addition, to nano plate with one diminution lower than 50 nm. While in procedure 2, the particles were spherical nanoparticles crystals with nanorods their sizes were (˂ 25) nm. The same features were seen in TEM images. The FTIR results showed strong bands are observed at (524.6 and 501.5) cm-1 for procedure 1 and 2, respectively, which attributed to Cd-O stretching vibrations. The XRD patterns of each procedure produce a mixture of nanoparticles: CdO and CdO 2 . The average crystallite size of NPs was: (14.74 and 13.97) nm for procedure 1 respectively, and (16.8 and 13.9) nm, respectively. From UV visible spectral, the absorption spectra exhibit strong absorption at 290 nm and 300 nm for procedures (1 and 2), respectively. Their energy band gaps were: (3 and 4.4) eV, respectively.

“…Cadmium oxide is an acute toxic (oral, inhalation, and dermal) material but it was used according to its special features and various applications [4]. A variety of thin films coating techniques have been used for the deposition of unloaded, loaded, and co-loaded CdO films "including chemical bath deposition [5] [6], pulsed laser deposition [7], vacuum evaporation [8], magnetron sputtering [9], metal organic chemical vapor deposition method" [10], successive ionic layers adsorption, and reaction technique [11], chemical spray pyrolysis [12], and sol gel technique [13]. Among all these, sol-gel spin coating method offers several benefits such as simplicity, the possibility of preparing various large as well as small area coatings, low-cost, homogeneity and high composition controlled way [4,14].…”

Transparent conducting pure and (Co + Zn) co-loaded CdO films were coated by sol-gel spin coating technique with various (cobalt + Zinc) co-loading concentrations. XRD analysis explained the polycrystalline nature of the coated samples with cubic crystal structure along (111) plane being the preferential orientation. The surface morphology and thickness of the prepared thin-films were analyzed by Field Effect Scanning Electron Microscopy (FESEM) and cross-sectional FESEM, respectively. The RMS surface roughness was analyzed by Atomic Force Microscopy AFM measurements. The existence of Cd, Co, Zn, and O elements was confirmed by “Energy-dispersive X-ray Spectroscopy (EDS) spectra”. The red-shift of energy-gap from 2.76 eV to 2.20 eV was carried out by using the Tauc;s and Davis-Mott mathematical relations, in high absorption regions. The shifting from the n-type to p-type semiconductor behavior for the coated samples was estimated by 4 points probe and average Hall coefficient value sign.
