“…The values of E g increase with the increase of Er 3+ content, confirming the decrease of particle size for samples with higher Er content. The decrease in particle size can be explained by the quantum confinement effect [39,40].…”

In the present work, the effect of doping zinc cobalt ferrite by different concentrations of Er 3+ on structural, optical, and magnetic properties was studied. Nanosized Zn 0.5 Co 0.5 Er x Fe 2−x O 4 (0 ≤ x ≤ 0.2) was synthesized by the coprecipitation method. XRD analysis confirmed the formation of one phase face FCC spinel structure belonging to the Fd3m space group. TEM exhibited that the particle size decreased with the increase of Er 3+ content, which is in agreement with XRD results. Two significant absorption bands from FTIR spectra were observed between 400 and 600 cm −1 . The band gap energy value obtained from UV-Vis increased with the increasing concentration of Er 3+ . The decrease of g-value is well correlated with the variation of particle size. All the VSM spectra reveal superparamagnetic behavior. The saturation magnetization decreases continuously while coercivity decreases abruptly with the increase of Er 3+ content. The results of this work show the possibility that zinc cobalt ferrite doped by erbium can be useful for magnetic resonance imaging as a biomedicine application.

“…Therefore, it can be summarized that bandgap engineering is possible by controlling the synthesis processes of II-VI group ternary alloy ZnMgS. This ternary alloy has successfully been synthesized by various physical techniques, such as molecular beam epitaxy [18,19], metalorganic vapor phase epitaxial growth [20], solid solution [15,21,22], sputtering [15], and chemical approach [23][24][25].…”

An Investigation on Structural and Optical Properties of Zn1−xMgxS Thin Films Deposited by RF Magnetron Co-Sputtering Technique

In this paper, Zn1−xMgxS thin films were co-sputtered on glass substrates using ZnS and MgS binary target materials under various applied RF power. The compositional ratio of Zn1−xMgxS films was varied by changing the RF power at an elevated temperature of 200 °C. The structural and optical properties were studied in detail. The structural analysis shows that the co-sputtered Zn1−xMgxS thin films have a cubic phase with preferred orientation along the (111) plane. The lattice constant and ionicity suggest the presence of a zincblende structure in Zn1−xMgxS thin films. Zn1−xMgxS thin films have transmittance over 76%. The extrapolation of optical characteristics indicates that direct bandgaps, ranging from 4.39 to 3.25 eV, have been achieved for the grown Zn1−xMgxS films, which are desirable for buffer or window layers of thin film photovoltaics.
