Conductivity tuning of the ITO sol-gel materials by adjusting the tin oxide concentration, morphology and the crystalline size

摘要: Abstract A facile epoxide-driven method has been used to synthesize a series of highly electrically conductive mesoporous indium tin oxide (ITO) sol-gel nanomaterials with different morphologies and particle sizes. By altering the Sn content, morphology size these materials undergo drastic change. The effect ultimately results in significant changes observed conductance materials. It became apparent that increasing dopant concentration In2O3 matrix resulted an increase average crystallite present material. Additionally, modifies which at low exhibit sponge-like microstructure gradually spherical-type architecture as increases. coupling changing observable difference conductivity. There was general conductivity correlated maximum being for sample 17 wt% Sn. Increasing above this point decrease This work provides simple tune ITO aerogels by simply modify within
