Investigation of half metallicity in Fe doped CdSe and Co doped CdSe materials

One-step hydrothermal synthesis of cobalt and potassium codoped CdSe quantum dots with high visible light photocatalytic activity

“…The non-doped CdSe quantum dots have a band gap of 1.6 eV and the doped CdSe quantum dots have a band gap of 1.75 eV. 27 Compared with that of the non-doped CdSe quantum dots, the absorption spectrum of the Co/K-doped quantum dots shows an obvious redshift trend. Due to the narrow band gap, the Co/ K-doped quantum dot photocatalyst could generate more excited electrons and holes when irradiated with visible light.…”

“…For instance, the materials were doped with transition metals such as Zn, Co, Mn and Cu, in order to change the lattice structure of the CdSe quantum dots. [27][28][29] Nevertheless, shortcomings of the transition metal doped materials include their poor thermostability, generated recombination centers of electrons and holes and the strict demand of instruments. Some of the newest studies suggest that the band gap of CdSe could be further narrowed by codoping various ions and that the photocatalytic activity could also be improved.…”

First-principles investigation of structural, elastic, electronic and magnetic properties of Be0.75Co0.25Y (YS, Se and Te) compounds

“…For instance, those properties of materials (non-magnetic and magnetic) [5][6][7][8] which were difficult to be achieved previously by experiments means or required a high degree of imagination are now possible to be modeled in virtual reality and be explained.…”

Iron Doped CdSe Films with Improved Photosensitivity and Stability for Use in a Liquid Junction Solar Cell

“…Shinde et al also developed CdFeSe films through galvanostatic method and reported maximum photoconversion efficiency of 0.38% with 46% FF. There are few other reports available on optimizing dopant concentration to modify the surface and the physical properties of CdFeSe composite films. − However, in any of the above reports, co-deposition mechanism and its correlation with the matrix morphology were not discussed. Furthermore, the stability study of the films toward photodegradation has neither been attempted.…”
