Abstract

Researchers have strategically designed a new approach for the development of co-doped TiO₂ with higher N^3- concentrations for a real synergistic and cooperative interaction between co-dopants. another ion should be introduced to improve the local crystal chemical environment for accommodating more nitrogen ions. In this scenario, the two co-dopants must interact closely with each other within a small vicinity to form defect-pairs or clusters. The impact of newly formed defect-pairs or clusters would be expected to behave as a new type of defect which not only has the special features of individual dopant but also effectively avoids the drawbacks of single doping. In the case of co-doped anatase TiO₂ nanocrystals
