Graphical Abstract
  • Abstract This study investigates the recovery of the B1 phase from the high-pressure B2 phase, at atmospheric pressure, in cadmium oxide (CdO) nanoparticles incorporated within sol–gel synthesized CdxZn1−xO (x = 0.40) composite thin films. The recovery process is investigated using electronic excitations
  • ; Introduction Zinc oxide (ZnO)-based thin films are of significant interest due to their wide bandgap value (3.37 eV at room temperature), transparent electrical conduction, and large excitonic binding energy (60 meV) [1]. In contrast, cadmium oxide (CdO) exhibits a lower bandgap of 2.2 eV, along with high
