(a) Transmission spectra in visible and near-IR regions for ITO films deposited at room temperature at fixed oxygen/argon ratio (0.03) and annealed at various temperatures (as-grown/100°C/200°C/300°C/400°C) and (b) average visible-light (400–800 nm) and near-IR (800–1200 nm) transmissions of films deposited using a fixed oxygen/argon ratio of 0.03 and annealed at various temperatures (as-grown/100°C/200°C/300°C/400°C).
