“…In the study of magnetic factors affecting magnetic ions, it is found that the size of ionic magnetism is related to the band gap width of the semiconductor formed. 33 The results show that the magnetic properties in materials are caused by vacancy defects caused by surface electron transitions in the environment. This surface vacancy is the reason for the ferromagnetic coupling of materials.…”

“…Table 1 illustrates the changes in peak position and FWHM through (111) orientation, cell parameter 'a', 'd' value, mean crystallite size (D) and micro-strain (ε) of Cd 0.9 Zn 0.1 S and Cd 0.87 Zn 0.1 Ni 0.03 S. Here, the crystallite size is derived from Scherrer relation [50], 0.9 λ/β cosθ. Microstrain is obtained from the relation [51], β cosθ/4. Both in the calculation of crystallite size and micro-strain, the used parameters β and θ were obtained from (111) orientation.…”

The present work describe the synthesis of Cd 0.9 Zn 0.1 S and Cd 0.87 Zn 0.1 Ni 0.03 S nanostructures by chemical co-precipitation method. The XRD profile proved the cubic crystal structure of the samples without any impurity related phases. The reduced size from 63 to 51 Å and the dissimilarities in lattice parameters and micro-strain has been discussed by Ni addition in Cd 0.87 Zn 0.1 Ni 0.03 S structure. The noticed anomalous optical studies and the elevated transmittance at Ni doped sample suggested them for the fabrication of efficient opto-electronic devices. The energy gap reduction during the substitution of Ni = 3% is explained by the generation of extra energy levels associated with defects within the two bands. The release of additional charge carriers, improved optical property, reduced particle size and more defect generation are responsible for the enhanced photo-catalytic performance of Ni doped Cd 0.9 Zn 0.1 S. The enhanced anti-bacterial capacity in Cd 0.87 Zn 0.1 Ni 0.03 S is described by the collective response of reduced particle size and higher reactive oxygen species (ROS) like O 2 ⋅− , H 2 O 2 and OH ⋅ generating capacity.
