We are the first to report a systematic study on the structural, optical and magnetic properties of cobalt and aluminum codoped CdS nanoparticles synthesized by simple co precipitation method. XRD patterns confirm the formation of single phase cubic structure for all the compositions. From diffuse reflectance spectra (DRS), three characteristic reflectance minima peaks present for all samples at 686,...
Diluted magnetic semiconductors (DMSs) such as transition metal TM-doped ZnO and TiO2 are attracting more and more attention due to their promising applications in spintronic devices. Ferromagnetism (FM) in these materials is often associated with ether free carriers or structural defects. Recently, it has been reported that codoping with hydrogen could be an effective way to tune the concentration...
Gd2O3:Eu3+, Tb3+ and Bi3+ ions co-doped Gd2O3:Eu3+, Tb3+ powders were synthesized by solvothermal reaction method. The crystalline structure, surface morphologies and phase transitions of these powders were investigated according to annealing process by using X-ray diffraction (XRD), field emission-scanning electron microscopy, photoluminescence spectroscopy (PL) and transmission electron microscopy...
