While integrating/doping atoms into the host matrix, few of the host's atoms are replaced by the dopant atoms. i.e lattice distortions. It leads to modifications in conductivity of the semiconducting materials. since Electrical conductivity in semiconductors depends on the concentration of electrons and holes as well as their mobility. With the metal doping, huge amount of electrons are available than holes. And those electrons and holes involve in Oxidation and reduction reactions. Consequently lesser recombination rate. I hope this would be helpful. Thank you
what if I doped in TiO2 with Vanadium? I tried several methods included hydrothermal and sol-gel but it still couldn't work even in UV light or Visible light
Adjust Doping Concentration, Investigate co-doping TiO2 with additional elements (e.g., nitrogen, carbon) along with vanadium , Fine-tune parameters such as temperature, pH, and reaction time
