“…In Table 2, the peak position and intensity of the more representative vibrational modes are set to get a better understanding of the exciton-phonon coupling strength behavior, which is represented by the intensity ratio of 2-LO to 1-LO modes (I 2LO /I 1LO ) of the semiconductor. This intensity ratio slightly decreases as Zn 2+ concentration increases, as shown in Figure 8, which is in line with some literature surveys for other dopants like Mn +2 [53]. From Table 2, it can be observed that the intensities of 1-LO and 2-LO are the highest for the Zn 0.2 Cd 0.8 S solid solution.…”

A simple ultrasonic radiation method was employed for the preparation of zinc and cadmium sulfide solid solution (ZnxCd1−xS; x = 0–0.25 wt.%) with the aim to investigate its efficiency for H2 production via a visible light-driven water-splitting reaction. The catalyst characterization by X-ray diffraction confirmed the formation of solid solution (ZnxCd1−xS) between CdS and ZnS phases. All catalysts exhibited hierarchical morphology (from SEM and TEM) formed by aggregated nanoparticles of ZnxCd1−xS solid solution with crystals showing mainly (111) planes of cubic CdS phase. The crystal size linearly decreased with an increase in Zn incorporation in the crystal lattice (from 4.37 nm to 3.72 nm). The ZnxCd1−xS photocatalysts showed a gradual increase in the H2 evolution, with an increase in the Zn concentration up to 0.2 wt.% making the most effective Zn0.2Cd0.8S catalyst toward H2 production. From the catalyst activity–structure correlation, it has been concluded that the twin-like CdS structure, the (111) plane and specific morphology are the main factors influencing the catalyst effectivity toward H2 production. All those factors compensated for the negative effect of an increase in band gap energy (Ebg) after ZnS incorporation into solid solution (from 2.21 eV to 2.34 eV). The effect of the catalyst morphology is discussed by comparing H2 evolution over unsupported and supported Zn0.2Cd0.8S solid solutions.

“…XRD pattern of Cu-NPs is well agreed with cubic nature of the metallic NP. [12,61,62] Broad diffraction peaks of CdS-NPs also correspond with cubic phase confinement associated with decreasing size of quantum crystals. [63] Baseline evenness in XRD along with low polydisperity index in DLS for both NPs signifies the purity and dispersity of the nanosuspensions.…”

The present investigation deals with wet chemical preparation and characterisation of copper (Cu) and cadmium sulphide (CdS) nanoparticles (NPs) (using UVÀvisible spectra, Fourier transform infra-red scattering, X-ray diffraction, dynamic light scattering, field emission scanning electron microscopy and transmission electron microscopy) and their effectivity on mitotic and meiotic cells of Nigella sativa L. (Ranunculaceae) in comparison to ethyl methanesulphonate (EMS) and gamma irradiations. The objective of the study is to foresee whether Cu-and CdS-NPs can induce similar type of chromosomal aberrations as that of EMS and gamma irradiations, or not. Dry seeds of N. sativa (2n D 12) are exposed to Cu-and CdS-NPs (0.25, 0.50 and 1.0 mg/ml; 3 and 6 h), EMS (0.25, 0.50 and 1.0%; 3 and 6 h) and doses of gamma irradiations (25, 50, 100, 200 and 300 Gy). Cu-NPs (range: 25.7 to 120.4 nm; 33.2 nm § 9.6) and CdS-NPs (range: 29.4 to 115.7 nm; 37.8 nm § 10.7) are both cubical to spherical in shape. NPs are found to induce similar responses as that of the studied conventional mutagens, in relation to physiological and chromosomal (mitotic and meiotic) attributes. Uptake of Cu-and CdS-NPs in seedlings is also studied using atomic absorption spectroscopy. Results suggest that Cu-and CdS-NPs can act as mutagenic agent, a pioneer report of its kind.

“…Separation of particles depends not only on the particle charge but also on the concentration of dopant ions in the host lattice. When the concentration of Fe 3+ ions exceeds the critical value, the charge repulsion between the particles were disabled which leads to coagulation and results in particle agglomeration [36].
