Electrical and optical characteristics of Sb-doped and annealed nanocrystalline SnO₂ thin films deposited in CBD techniques

摘要

Tin oxide (SnO2) thin films doped with antimony were grown on plane glass substratesusing chemical bath deposition (CBD) technique. Precursor chemicals of stannic chlorideand sodium hydroxide were used to supply tin and oxygen ions respectively andtriethanolamine (TEA) was added as a complexant. Sb doping was accomplished byadding little quantity antimony chloride that enabled orderly growth of ternary Sn1-xSbxO2film where 0 80 %) in visible region andalso high absorbance (A > 0.2) in NIR. Annealing also increased electrical conductivity inall the temperatures considered.
