Abstract

Transparent and electromagnetic (EM) shielding Co-doped SnO₂ (CTO) thin films were fabricated using ultrasonic-assisted spray pyrolysis deposition. Structural and chemical investigations showed that the Co²⁺ ions were substitutionally incorporated into the Sn⁴⁺ lattice sites of the SnO₂ crystal and that the Co concentration increased with increasing the Co source content. The incorporated Co ions acted as a magnetic dopant and as an electrical acceptor to compensate for the free charge carriers in SnO₂. Co-doping could modulate the two conflicting efficiencies of the EM shielding performance in the frequency range of 1.5–18 GHz and the infrared transmittance of the SnO₂ thin films.
