Influence of oxygen vacancy defects and cobalt doping on optical, electronic and photocatalytic properties of ultrafine SnO2-δ nanocrystals
Processing and Application of Ceramics
Ultrafine pure and cobalt doped SnO 2-δ nanocrystals (Sn 1-x Co x O 2-δ , 0 ≤ x ≤ 0.05) were synthesized by microwave-assisted hydrothermal method. The as-prepared nanocrystals have single phase tetragonal rutile structure. With increase of Co content (x > 0.01), Co entered into SnO 2 lattice in mixed Co 2+ /Co 3+ state. Pronounced blue shift of the band gap with cobalt doping originated from the combined effect of quantum confinement and Burnstain-Moss shift.
