Effects of Lanthanum/Gadolinium Doping on Crystal Structures, Electronic Properties and Optical Characteristics of Bismuth Tungstate Photocatalyst: DFT Approach

First principles calculations are employed to evaluate the crystal structures, electronic properties, optical properties and carrier effective masses of pure and Lanthanum (La) or Gadolinium (Gd) doped bismuth tungstate (Bi2WO6). The calculated results reveal that La or Gd dopants do not modify the...
