Electrical, photoluminescence and optical investigation of ZnO nanoparticles sintered at different temperatures

Structural, optical, and dielectric properties of hydrothermally synthesized SnO2 nanoparticles, Cu/SnO2, and Fe/SnO2 nanocomposites

“…This behavior is crucial for understanding the absorption and reflection of light in materials. The detected positive slope for SnO 2 nanoparticles is consistent with prior studies for other materials such as ZnO nanoparticles, Zn 1−x Al x O, and Zn 1−x−y Fe x M y O ceramics [48][49][50]. The numerical values of (N/m * ) and e L are calculated from the slope (absolute value) and intercept of the fitted equations (inserted into the plot) for each sample.…”

Improved mechanical, optical, and electrical properties of chitosan films with the synergistic reinforcing effect of carbon nanotubes and reduced graphene oxide for potential optoelectronic applications

“…Therefore, molecules with a high quantity of oxygen can emit light since oxygen atoms are electron-rich and can be considered luminescence centers. The green emission at 500-525 nm has been attributed to a donor-acceptor recombination or transition from the conduction band to oxygen antisites [102]. In an ordered compound, the atoms of different type exchange positions generate an antisite defect; the crystallographic defects disrupt the regular patterns or arrangement of atoms in crystalline solids.…”
